f91ee129a7 Simplify optional WITH handling in CREATE USER, ALTER USER, CREATE
GROUP.  Make WITH optional in CREATE DATABASE for consistency.

7882179994 The normal operation of our servers is to have tcpip_sockets enabled,
but occasionally I may need to shut down the server and restart it
w/o tcpip sockets. Postmaster has the -i option to turn on tcpip
connections, but it wasn't immediately clear how to easily or
temporarily turn it off (when it's been enabled in postgresql.conf).

In fact, it wasn't clear to me until digging in to postmaster.c that
I could pass '-c tcpip_socket=false' or '--tcpip_socket=false'.
(And then of course when I looked more closely at the man page I
realized I'd missed the proper part of the documentation.) What I'd
been looking for is a flag that would have the opposite effect of
'-i', and it's conceivable that others will be looking for specific
flags to do the opposite of '-F' and '-S'.

I was preparing to add options to postmaster until I realized that
maybe the solution is just to add some documentation.

If you'd rather have 1 character options to accomplish this, I'd be
happy to do that-- adding those 9 lines of code is definitely within
my ability. :)  (Although, the "right" letter to be the opposite of -S
isn't clear to me, since -s is already taken.)

ea01a451cc Implement SQL99 OVERLAY(). Allows substitution of a substring in a string.
Implement SQL99 SIMILAR TO as a synonym for our existing operator "~".
Implement SQL99 regular expression SUBSTRING(string FROM pat FOR escape).
 Extend the definition to make the FOR clause optional.
 Define textregexsubstr() to actually implement this feature.
Update the regression test to include these new string features.
 All tests pass.
Rename the regular expression support routines from "pg95_xxx" to "pg_xxx".
Define CREATE CHARACTER SET in the parser per SQL99. No implementation yet.

d60f10b0e7 Add optional "validator" function to languages that can validate the
function body (and other properties) as a function in the language
is created.  This generalizes ad hoc code that already existed for
the built-in languages.

The validation now happens after the pg_proc tuple of the new function
is created, so it is possible to define recursive SQL functions.

Add some regression test cases that cover bogus function definition
attempts.

f0811a74b3 Merge the last few variable.c configuration variables into the generic
GUC support.  It's now possible to set datestyle, timezone, and
client_encoding from postgresql.conf and per-database or per-user
settings.  Also, implement rollback of SET commands that occur in a
transaction that later fails.  Create a SET LOCAL var = value syntax
that sets the variable only for the duration of the current transaction.
All per previous discussions in pghackers.

f69bc37be8 Make operators have their own comments separate from those of the
underlying function; but cause psql's \do to show the underlying
function's comment if the operator has no comment of its own, to preserve
the useful functionality of the original behavior.  Also, implement
COMMENT ON SCHEMA.  Patch from Rod Taylor.

2822788993 Accept SET SESSION AUTHORIZATION DEFAULT and RESET SESSION AUTHORIZATION
to reset session userid to the originally-authenticated name.  Also,
relax SET SESSION AUTHORIZATION to allow specifying one's own username
even if one is not superuser, so as to avoid unnecessary error messages
when loading a pg_dump file that uses this command.  Per discussion from
several months ago.

19b31e0713 Oops, wrong commit on previous. It was:
The attached patch allows views to have default values. You can't
specify a default value within a CREATE VIEW statement, it must be
done using ALTER TABLE ... ALTER COLUMN ... SET DEFAULT after the
view has already been created. Most of the hard work was done by
Tom Lane, I just patched pg_dump and updated the documentation.

c05f29e895 Augment the date/time examples in the User's Guide to reflect the newer
capabilities of specifying time zones as intervals per SQL9x.
Put refentrytitle contents on the same line as the tag.
 Otherwise, leading whitespace is propagated into the product, which
 (at least) messes up the ToC layout.
Remove (some) docinfo tags containing dates. Best to omit if the dates
 are not accurate; maybe use CVS dates instead or leave them out.

b0bcf8aab2 Restructure AclItem representation so that we can have more than eight
different privilege bits (might as well make use of the space we were
wasting on padding).  EXECUTE and USAGE bits for procedures, languages
now are separate privileges instead of being overlaid on SELECT.  Add
privileges for namespaces and databases.  The GRANT and REVOKE commands
work for these object types, but we don't actually enforce the privileges
yet...

6d6ca2166c Change naming rule for ON SELECT rules of views: they're all just

201737168c pg_trigger's index on tgrelid is replaced by a unique index on
(tgrelid, tgname).  This provides an additional check on trigger name
uniqueness per-table (which was already enforced by the code anyway).
With this change, RelationBuildTriggers will read the triggers in
order by tgname, since it's scanning using this index.  Since a
predictable trigger ordering has been requested for some time, document
this behavior as a feature.  Also document that rules fire in name
order, since yesterday's changes to pg_rewrite indexing cause that too.

b3120804ad Rule names are now unique per-relation, rather than unique globally.
DROP RULE and COMMENT ON RULE syntax adds an 'ON tablename' clause,
similar to TRIGGER syntaxes.  To allow loading of existing pg_dump
files containing COMMENT ON RULE, the COMMENT code will still accept
the old syntax --- but only if the target rulename is unique across
the whole database.

6cef5d2549 Operators live in namespaces. CREATE/DROP/COMMENT ON OPERATOR take
qualified operator names directly, for example CREATE OPERATOR myschema.+
( ... ).  To qualify an operator name in an expression you need to write
OPERATOR(myschema.+) (thanks to Peter for suggesting an escape hatch).
I also took advantage of having to reformat pg_operator to fix something
that'd been bugging me for a while: mergejoinable operators should have
explicit links to the associated cross-data-type comparison operators,
rather than hardwiring an assumption that they are named < and >.

902a6a0a4b Restructure representation of aggregate functions so that they have pg_proc
entries, per pghackers discussion.  This fixes aggregates to live in
namespaces, and also simplifies/speeds up lookup in parse_func.c.
Also, add a 'proimplicit' flag to pg_proc that controls whether a type
coercion function may be invoked implicitly, or only explicitly.  The
current settings of these flags are more permissive than I would like,
but we will need to debate and refine the behavior; for now, I avoided
breaking regression tests as much as I could.

4bdb4be62e Divide functions into three volatility classes (immutable, stable, and
volatile), rather than the old cachable/noncachable distinction.  This
allows indexscan optimizations in many places where we formerly didn't.
Also, add a pronamespace column to pg_proc (it doesn't do anything yet,
however).

01c76f7411 Ok. Updated patch attached.
- domain.patch -> source patch against pgsql in cvs
- drop_domain.sgml and create_domain.sgml -> New doc/src/sgml/ref docs

- dominfo.txt -> basic domain related queries I used for testing
[ ADDED TO /doc]

Enables domains of array elements -> CREATE DOMAIN dom int4[3][2];

Uses a typbasetype column to describe the origin of the domain.

Copies data to attnotnull rather than processing in execMain().

Some documentation differences from earlier.

If this is approved, I'll start working on pg_dump, and a \dD <domain>
option in psql, and regression tests.  I don't really feel like doing
those until the system table structure settles for pg_type.


CHECKS when added, will also be copied to to the table attributes.  FK
Constraints (if I ever figure out how) will be done similarly.  Both
will lbe handled by MergeDomainAttributes() which is called shortly
before MergeAttributes().

03194432de I attach a version of my toast-slicing patch, against current CVS
(current as of a few hours ago.)

This patch:

1. Adds PG_GETARG_xxx_P_SLICE() macros and associated support routines.

2. Adds routines in src/backend/access/tuptoaster.c for fetching only
necessary chunks of a toasted value. (Modelled on latest changes to
assume chunks are returned in order).

3. Amends text_substr and bytea_substr to use new methods. It now
handles multibyte cases -and should still lead to a performance
improvement in the multibyte case where the substring is near the
beginning of the string.

4. Added new command: ALTER TABLE tabname ALTER COLUMN colname SET
STORAGE {PLAIN | EXTERNAL | EXTENDED | MAIN} to parser and documented in
alter-table.sgml. (NB I used ColId as the item type for the storage
mode string, rather than a new production - I hope this makes sense!).
All this does is sets attstorage for the specified column.

4. AlterTableAlterColumnStatistics is now AlterTableAlterColumnFlags and
handles both statistics and storage (it uses the subtype code to
distinguish). The previous version of my patch also re-arranged other
code in backend/commands/command.c but I have dropped that from this
patch.(I plan to return to it separately).

5. Documented new macros (and also the PG_GETARG_xxx_P_COPY macros) in
xfunc.sgml. ref/alter_table.sgml also contains documentation for ALTER
COLUMN SET STORAGE.
