* Re-introduce the yylex filter function formerly used to support UNIONTom Lane2006-05-27
| | | | | | | JOIN, which I removed in a recent fit of over-optimism that we wouldn't have any future use for it. Now it's needed to support disambiguating WITH CHECK OPTION from WITH TIME ZONE. As proof of concept, add stub grammar productions for WITH CHECK OPTION.
* Remove the stub support we had for UNION JOIN; per discussion, this isTom Lane2006-03-07
| | | | | | not likely ever to be implemented seeing it's been removed from SQL2003. This allows getting rid of the 'filter' version of yylex() that we had in parser.c, which should save at least a few microseconds in parsing.

* Tag appropriate files for rc3PostgreSQL Daemon2004-12-31
| | | | | | | | Also performed an initial run through of upgrading our Copyright date to extend to 2005 ... first run here was very simple ... change everything where: grep 1996-2004 && the word 'Copyright' ... scanned through the generated list with 'less' first, and after, to make sure that I only picked up the right entries ...

| | | | *got* to be pointless.
* Infrastructure for deducing Param types from context, in the same wayTom Lane2003-04-29
| | | | | | | | | | | that the types of untyped string-literal constants are deduced (ie, when coerce_type is applied to 'em, that's what the type must be). Remove the ancient hack of storing the input Param-types array as a global variable, and put the info into ParseState instead. This touches a lot of files because of adjustment of routine parameter lists, but it's really not a large patch. Note: PREPARE statement still insists on exact specification of parameter types, but that could easily be relaxed now, if we wanted to do so.
* Put back encoding-conversion step in processing of incoming queries;Tom Lane2003-04-27
| | | | | | | | | | I had inadvertently omitted it while rearranging things to support length-counted incoming messages. Also, change the parser's API back to accepting a 'char *' query string instead of 'StringInfo', as the latter wasn't buying us anything except overhead. (I think when I put it in I had some notion of making the parser API 8-bit-clean, but seeing that flex depends on null-terminated input, that's not really ever gonna happen.)

* Scanner performance improvementsPeter Eisentraut2002-04-20
| | | | | | | | Use flex flags -CF. Pass the to-be-scanned string around as StringInfo type, to avoid querying the length repeatedly. Clean up some code and remove lex-compatibility cruft. Escape backslash sequences inline. Use flex-provided yy_scan_buffer() function to set up input, rather than using myinput().

* Arrange that no database accesses are attempted during parser() --- thisTom Lane2000-10-07
| | | | | | | | | | | | | | | took some rejiggering of typename and ACL parsing, as well as moving parse_analyze call out of parser(). Restructure postgres.c processing so that parse analysis and rewrite are skipped when in abort-transaction state. Only COMMIT and ABORT statements will be processed beyond the raw parser() phase. This addresses problem of parser failing with database access errors while in aborted state (see pghackers discussions around 7/28/00). Also fix some bugs with COMMIT/ABORT statements appearing in the middle of a single query input string. Function, operator, and aggregate arguments/results can now use full TypeName production, in particular foo[] for array types. DROP OPERATOR and COMMENT ON OPERATOR were broken for unary operators. Allow CREATE AGGREGATE to accept unquoted numeric constants for initcond.

| | | | | | | | | | lists are now plain old garden-variety Lists, allocated with palloc, rather than specialized expansible-array data allocated with malloc. This substantially simplifies their handling and eliminates several sources of memory leakage. Several basic types of erroneous queries (syntax error, attempt to insert a duplicate key into a unique index) now demonstrably leak zero bytes per query.
