I checked into this and it seems that what we'd need to do is backport
some subset of these 7.4 changes:
2003-09-13 22:18 tgl
* contrib/seg/: Makefile, README.seg, seg.c, seg.sql.in,
segparse.y, segscan.l, expected/seg.out: Make contrib/seg work with
flex 2.5.31. Fix it up to have a real btree operator class, too,
since in PG 7.4 you can't GROUP without one.
2003-09-13 21:52 tgl
* contrib/cube/: Makefile, README.cube, cube.c, cube.sql.in,
cubeparse.y, cubescan.l, expected/cube.out: Make contrib/cube work
with flex 2.5.31. Fix it up to have a real btree operator class,
too, since in PG 7.4 you can't GROUP without one.
2003-09-14 14:44 tgl
* contrib/: tsearch/parser.l, tsearch2/wordparser/parser.l:
Persuade tsearch/tsearch2 to work (or at least pass their
regression tests) when using flex 2.5.31. The fix is to *not* try
to use palloc and pfree for allocations within the lexer; when you
do that, the yy_buffer_stack gets freed at inopportune times. The
code is already set up to do manual deallocation, so I see no
particular advantage to using palloc anyway.
This is probably not worth doing. We're really only maintaining 7.3 for
legacy platforms (the only one I care about is RHEL3 ;-)) and a legacy
platform is likely to have an old flex. It's a tad annoying to lose
buildfarm coverage on it though ...
