90edb265e3 Implement SQL99 CREATE CAST and DROP CAST statements.
Also implement alternative forms to expose the PostgreSQL CREATE FUNCTION
 features.
Implement syntax for READ ONLY and READ WRITE clauses in SET TRANSACTION.
 READ WRITE is already implemented (of course).
Implement syntax for "LIKE table" clause in CREATE TABLE. Should be fairly
 easy to complete since it resembles SELECT INTO.
Implement MATCH SIMPLE clause for foreign key definitions. This is explicit
 SQL99 syntax for the default behavior, so we now support it :)
Start implementation of shorthand for national character literals in
 scanner. For now, just swallow the leading "N", but sometime soon let's
 figure out how to pass leading type info from the scanner to the parser.
 We should use the same technique for binary and hex bit string literals,
 though it might be unusual to have two apparently independent literal
 types fold into the same storage type.

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.
