Greetings, To all those who helped out with this problem, I'm sorry it took me so long to respond. For the record, the matter is solved, at least for us, but we had to repeat a lot of things to make sure. First, the "out of memory" problem repeated itself when restoring that single table, after doing a schema-only restore and removing all foreign key constraints. Second, the other weirdness on this table was a couple of constraints to make sure that the three arrays on each row were of the same length. But that was not the problem. It turned out that the backup file was the problem. Plus, I'm convinced that this was our mistake, someone simply didn't see an error message during backup or some copy of the file. Also, we should have already repeated the backup and maybe we didn't. We did a new custom dump from within latest pgadmin III, and that one restored just fine (using the same old 9.1.8 pg_restore). It could have been a bug in pg_dump 9.1.8 since the good backup was from a newer version. But this didn't seem so likely and because repeating a full backup would force us to keep the original database on the server for a few more days (dumps take so long) we didn't do it. We did however a dump of that single table with pg_dump 9.1.8 and that one also restored just fine. Our immediate practical problem is over. The only complaint would be that the "out of memory" message is unfriendly. If you would find useful that we make some additional tests, or some observation of the file, we would be glad to return the help.
