This commit fixes psql, pg_dump, and the information schema to be
consistent with the backend changes which I made as part of commit
be90032e0d1cf473bdd99aee94218218f59f29f1, and also includes a
related documentation tweak.
Shigeru Hanada, with slight adjustment.
Use collencoding = -1 to represent such a collation in pg_collation.
We need this to make the "default" entry work sanely, and a later
patch will fix the C/POSIX entries to be represented this way instead
of duplicating them across all encodings. All lookup operations now
search first for an entry that's database-encoding-specific, and then
for the same name with collencoding = -1.
Also some incidental code cleanup in collationcmds.c and pg_collation.c.
- ALTER FOREIGN DATA WRAPPER with HANDLER
- ALTER TABLE VALIDATE CONSTRAINT
- ALTER TYPE ADD VALUE
- COPY with ENCODING and FORCE NOT NULL
- CREATE FOREIGN DATA WRAPPER with HANDLER
- CREATE TRIGGER ... INSTEAD OF
The original design of pg_available_extensions did not consider the
possibility of version-specific control files. Split it into two views:
pg_available_extensions shows information that is generic about an
extension, while pg_available_extension_versions shows all available
versions together with information that could be version-dependent.
Also, add an SRF pg_extension_update_paths() to assist in checking that
a collection of update scripts provide sane update path sequences.
- collowner field
- CREATE COLLATION
- ALTER COLLATION
- DROP COLLATION
- COMMENT ON COLLATION
- integration with extensions
- pg_dump support for the above
- dependency management
- psql tab completion
- psql \dO command
This follows recent discussions, so it's quite a bit different from
Dimitri's original. There will probably be more changes once we get a bit
of experience with it, but let's get it in and start playing with it.
This is still just core code. I'll start converting contrib modules
shortly.

This patch adds the server infrastructure to support extensions.
There is still one significant loose end, namely how to make it play nice
with pg_upgrade, so I am not yet committing the changes that would make
all the contrib modules depend on this feature.
In passing, fix a disturbingly large amount of breakage in
AlterObjectNamespace() and callers.

Foreign tables are a core component of SQL/MED. This commit does
not provide a working SQL/MED infrastructure, because foreign tables
cannot yet be queried. Support for foreign table scans will need to
be added in a future patch. However, this patch creates the necessary
system catalog structure, syntax support, and support for ancillary
operations such as COMMENT and SECURITY LABEL.
Shigeru Hanada, heavily revised by Robert Haas
Allow INSERT INTO, UPDATE, and DELETE FROM to be completed with
either the name of a table (as before) or the name of a view with
an appropriate INSTEAD OF rule.
Along the way, allow CREATE TRIGGER to be completed with INSTEAD OF,
as well as BEFORE and AFTER.

This adds support for changing the schema of a conversion, operator,
operator class, operator family, text search configuration, text search
dictionary, text search parser, or text search template.
Dimitri Fontaine, with assorted corrections and other kibitzing.
Completion is supported in the context of \set and when interpolating
a variable value using :foo etc.
In passing, fix some places in tab-complete.c that weren't following
project style for comment formatting.

This is intended as infrastructure to support integration with label-based
mandatory access control systems such as SE-Linux. Further changes (mostly
hooks) will be needed, but this is a big chunk of it.

to be initialized with proper values. Affected parameters are
fillfactor, analyze_threshold, and analyze_scale_factor.
Especially uninitialized fillfactor caused inefficient page usage
because we built a StdRdOptions struct in which fillfactor is zero
if any reloption is set for the toast table.
In addition, we disallow toast.autovacuum_analyze_threshold and
toast.autovacuum_analyze_scale_factor because we didn't actually
support them; they are always ignored.

Analysis by Tom Lane and Alvaro Herrera. Patch by me.
Backpatch to 8.4.
Add missing completions for:
- ALTER SEQUENCE name OWNER TO
- ALTER TYPE name RENAME TO
- ALTER VIEW name ALTER COLUMN
- ALTER VIEW name OWNER TO
- ALTER VIEW name SET SCHEMA
Fix wrong completions for:
- ALTER FUNCTION/AGGREGATE name (arguments) ...
"(arguments)" has been ignored.
- ALTER ... SET SCHEMA
"SCHEMA" has been considered as a variable name.
Newly supported syntax are:
- ALTER {TABLE|INDEX|TABLESPACE} {SET|RESET} with options
- ALTER TABLE ALTER COLUMN {SET|RESET} with options
- ALTER TABLE ALTER COLUMN SET STORAGE
- CREATE INDEX CONCURRENTLY
- CREATE INDEX ON (without name)
- CREATE INDEX ... USING with pg_am.amname instead of hard-corded names
- CREATE TRIGGER with events
- DROP AGGREGATE function with arguments
In addition, add support for a "payload" string to be passed along with
each notify event.
This implementation should be significantly more efficient than the old one,
and is also more compatible with Hot Standby usage. There is not yet any
facility for HS slaves to receive notifications generated on the master,
although such a thing is possible in future.
Joachim Wieland, reviewed by Jeff Davis; also hacked on by me.
Attributes can now have options, just as relations and tablespaces do, and
the reloptions code is used to parse, validate, and store them. For
simplicity and because these options are not performance critical, we store
them in a separate cache rather than the main relcache.
Thanks to Alex Hunsaker for the review.
ASCII-art style of table output to be upgraded to use Unicode box drawing
characters if desired. By default, psql will use the Unicode characters
whenever client_encoding is UTF8.
The patch forces linestyle=ascii in pg_regress usage, ensuring we don't
break the regression tests in Unicode locales.

wrappers (similar to procedural languages). This way we don't need to retain
the nearly empty libraries, and we are more free in how to implement the
wrapper API in the future.
This doesn't do any remote or external things yet, but it gives modules
like plproxy and dblink a standardized and future-proof system for
managing their connection information.
