Dear Gurus,

Version: PostgreSQL 7.3.3
Log:
%----------------------- cut here -----------------------%
tir=3D# CREATE INDEX ajanlat_cikk ON ajanlat (antinuller(cikk),
antinuller(minoseg), tol);
ERROR:  parser: parse error at or near "," at character 55
tir=3D# CREATE INDEX ajanlat_szolg ON ajanlat (antinuller(szolgaltatas), to=
l);
ERROR:  parser: parse error at or near "," at character 64
%----------------------- cut here -----------------------%

I'm not sure what happened, I'm quite sure it worked before, even with
7.3.3. The index was there and probably worked, but accidentally dropped it
and can't recreate.
May it be something in postgresql.conf (fumbled with it recently)?
May it be a bug in 7.3.3 (despite my memories)?

Relevant definitions:

CREATE FUNCTION antinuller (int4) RETURNS int4 AS '
