Jan,
Have you any ideas on this?
We get a rule output by pg_dump like :-
CREATE RULE "_RETsongs" AS ON SELECT TO "songs" WHERE DO INSTEAD SELECT "t"."artist", "t"."song", "t"."trackno",
"d"."cdname" FROM "disks" "d", "tracks" "t" WHERE "d"."diskid" = "t"."diskid";
from a view defined like so:-
CREATE VIEW songs AS SELECT t.artist, t.song, t.trackno, d.cdname FROM disks d, tracks t WHERE d.diskid = t.diskid;
Note the WHERE keyword in line 3 of the rule define.
>From "./src/backend/utils/adt/ruleutils.c" line 662 of 1814
/* If the rule has an event qualification, add it */ if (ev_qual == NULL) ev_qual = "";
if (strlen(ev_qual) > 0) { Node *qual; Query *query; QryHier
qh;
.
. strcat(buf, " WHERE "); strcat(buf, get_rule_expr(&qh, 0, qual, TRUE)); }
strcat(buf, " DO ");
/* The INSTEAD keyword (if so) */ if (is_instead) strcat(buf, "INSTEAD ");
We put the WHERE in if strlen(ev_qual) > 0
I've not yet followed this back any further.
Keith.

The problem is that views are dumped with anm extraneous "WHERE"

Which causes this error and the rule (View) is not Created.
I don't know how the where clause gets in there but if you
edit the dump before restoring all is OK.
