* Create a GUC variable REGEX_FLAVOR to control the type of regularTom Lane2003-02-06
| | | | | | | | expression accepted by the regex operators, per discussion yesterday. Along the way, reduce deadlock_timeout from PGC_POSTMASTER to PGC_SIGHUP category. It is probably best to insist that all backends share the same setting, but that doesn't mean it has to be frozen at startup.
* Replace regular expression package with Henry Spencer's latest versionTom Lane2003-02-05
| | | | | | | (extracted from Tcl 8.4.1 release, as Henry still hasn't got round to making it a separate library). This solves a performance problem for multibyte, as well as upgrading our regexp support to match recent Tcl and nearly match recent Perl.
* Bring SIMILAR TO and SUBSTRING into some semblance of conformance withTom Lane2002-09-22
| | | | | | | the SQL99 standard. (I'm not sure that the character-class features are quite right, but that can be fixed later.) Document SQL99 and POSIX regexps as being different features; provide variants of SUBSTRING for each.

* Search the existing regular expression cache as a ring buffer.Thomas G. Lockhart2002-06-15
| | | | | | | | | Will optimize the case for repeated calls for the same expression, which seems to be the most common case. Formerly, always searched from the first entry. May want to look at the least-recently-used algorithm to make sure it is identifying the right slots to reclaim. Seems silly to do math when it seems that we could simply use an incrementing counter...
* Implement SQL99 OVERLAY(). Allows substitution of a substring in a string.Thomas G. Lockhart2002-06-11
| | | | | | | | | | | 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.

* Fix misuse of StrNCpy to copy and add null to non-null-terminated data.Tom Lane2000-07-07
| | | | | | | Does not work since it fetches one byte beyond the source data, and when the phase of the moon is wrong, the source data is smack up against the end of backend memory and you get SIGSEGV. Don't laugh, this is a fix for an actual user bug report.
* Functions on 'text' type updated to new fmgr style. 'text' isTom Lane2000-07-06

* Update textin() and textout() to new fmgr style. This is just phaseTom Lane2000-07-05
| | | | | one of updating the whole text datatype, but there are so dang many calls of these two routines that it seems worth a separate commit.
