Second cut attached. This one just adds a boolean option to the existing

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.)

OK, the attached documentation patch provides some simple examples of
use of tablename as a parameter, %ROWTYPE and %TYPE.

In the end I decided that the documentation is literally correct, but
hard to follow without any examples explicitly showing the use of a
table name as a parameter.

133df7ce70 Add LOCALTIME and LOCALTIMESTAMP functions per SQL99 standard.
Remove ODBC-compatible empty parentheses from calls to SQL99 functions
 for which these parentheses do not match the standard.
Update the ODBC driver to ensure compatibility with the ODBC standard
 for these functions (e.g. CURRENT_TIMESTAMP, CURRENT_USER, etc).
Include a new appendix in the User's Guide which lists the labeled features
 for SQL99 (the labeled features replaced the "basic", "intermediate",
 and "advanced" categories from SQL92). features.sgml does not yet split
 this list into "supported" and "unsupported" lists.

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.
