pg_dump && aggregate bug
Hi
I have :
CREATE FUNCTION "first_cat" (text,text) RETURNS text AS 'SELECT CASE WHEN
$1 IS NULL THEN $2 ELSE $1 END' LANGUAGE 'sql';
and :
CREATE AGGREGATE first ( BASETYPE = text, SFUNC = first_cat, STYPE = text);
when I dump my database, in the dump file, the aggregate becomes :
CREATE AGGREGATE first ( BASETYPE = text, SFUNC = first_cat, STYPE = text,
INITCOND = '' );
which is *not* the same as you may imagine...
To dump my database, I use :
pg_dump -c
and I use :
PostgreSQL 7.2.1 on i386-portbld-freebsd4.5, compiled by GCC 2.95.3
I believe it lies around lines 3860 - 3864 of src/bin/pg_dump/pg_dump.c,
but I don't find what's wrong with it.

Ooops. This seems to be fixed already in current sources, but I think
a back-patch to 7.2 may be warranted. Try this around line 1912:
agginfo[i].aggbasetype = strdup(PQgetvalue(res, i, i_aggbasetype));
- agginfo[i].agginitval = strdup(PQgetvalue(res, i, i_agginitval));
+ if (PQgetisnull(res, i, i_agginitval))
+ agginfo[i].agginitval = NULL;
+ else
+ agginfo[i].agginitval = strdup(PQgetvalue(res, i, i_agginitval));
agginfo[i].usename = strdup(PQgetvalue(res, i, i_usename));

worked, thanks.
I wonder if it could go into a possible 7.1.2 if there is one ? :)
