Include updates for the comment.sql regression test. Implement SET SESSION CHARACTERISTICS and SET DefaultXactIsoLevel. Implement SET SESSION CHARACTERISTICS TRANSACTION COMMIT and SET AutoCommit in the parser only. Need to add code to actually do something. Implement WITHOUT TIME ZONE type qualifier. Define SCHEMA keyword, along with stubbed-out grammar. Implement "[IN|INOUT|OUT] [varname] type" function arguments in parser only; INOUT and OUT throws an elog(ERROR). Add PATH as a type-specific token, since PATH is in SQL99 to support schema resource search and resolution.
