I've bumped the system catalog version number and committed changes
which:
 o implement LIKE/ESCAPE and related clauses
 o implement a case-insensitive ILIKE and related clauses
 o allow embedded double-quotes in double-quoted identifers
 o implement CREATE/DROP SCHEMA as a synonym for CREATE DATABASE

All (more or less ;) per SQL99 standard, with the SCHEMA stuff just a
stopgap (afaik others are planning real work in this area). A few other
fixups too...

 From the CVS logs:

Support SQL99 embedded double-quote syntax for quoted identifiers.
Allow this in the parser and in pg_dump, but it is probably not enough
 for a complete solution. 
Better to have the feature started then never here.

Implement LIKE/ESCAPE. Change parser to use like()/notlike() 
 rather than the "~~" operator; this made it easy to add ESCAPE
features.
Implement ILIKE, NOT ILIKE, and the ESCAPE clause for them. 
 afaict this is not MultiByte clean, but lots of other stuff isn't
either.
Fix up underlying support code for LIKE/NOT LIKE. 
 Things should be faster and does not require internal string copying.
Update regression test to add explicit checks for 
 LIKE/NOT LIKE/ILIKE/NOT ILIKE.
Remove colon and semi-colon operators as threatened in 7.0.
Implement SQL99 COMMIT/AND NO CHAIN. 
 Throw elog(ERROR) on COMMIT/AND CHAIN per spec 
 since we don't yet support it.
Implement SQL99 CREATE/DROP SCHEMA as equivalent to CREATE DATABASE.
 This is only a stopgap or demo since schemas will have another 
 implementation soon.
Remove a few unused production rules to get rid of warnings 
 which crept in on the last commit. 
Fix up tabbing in some places by removing embedded spaces.

LIKE/ESCAPE et al, initdb required!
