     Repair bug in regexp split performance improvements. (details)

 Commit f7d0343ead29cd3e44eccd1c8b7cc291b79209fe by rhodiumtoad

 Repair bug in regexp split performance improvements.
 Commit c8ea87e4b introduced a temporary conversion buffer for substrings
 extracted during regexp splits. Unfortunately the code that sized it was
 failing to ignore the effects of ignored degenerate regexp matches, so
 for regexp_split_* calls it could under-size the buffer in such cases.
 Fix, and add some regression test cases (though those will only catch
 the bug if run in a multibyte encoding).
 Backpatch to 9.3 as the faulty code was.
 Thanks to the PostGIS project, Regina Obe and Paul Ramsey for the report
 (via IRC) and assistance in analysis. Patch by me.

 The file was modified   src/test/regress/expected/strings.out
 The file was modified   src/test/regress/sql/strings.sql
