OK, now I will answer my own question. It seems that ALTER TABLE MyCoolTable_1 DISABLE TRIGGER trg_foo_1 ; is a no-op when it is currently disabled.
And so no "txn id" is "needed". When I alternate DISable and ENable statements, it behaves as I expect . . . Start Transaction; DO $$ BEGIN raise info '%', txid_current(); END $$; ALTER TABLE MyCoolTable_1 DISABLE TRIGGER trg_foo_1 ; Commit; Start Transaction; ALTER TABLE MyCoolTable_1 ENABLE TRIGGER trg_foo_1 ; Commit; Start Transaction; DO $$ BEGIN raise info '%', txid_current(); END $$; ALTER TABLE MyCoolTable_1 DISABLE TRIGGER trg_foo_1 ; Commit; Start Transaction; ALTER TABLE MyCoolTable_1 ENABLE TRIGGER trg_foo_1 ; Commit; Start Transaction; DO $$ BEGIN raise info '%', txid_current(); END $$; ALTER TABLE MyCoolTable_1 DISABLE TRIGGER trg_foo_1 ; Commit; Start Transaction; ALTER TABLE MyCoolTable_1 ENABLE TRIGGER trg_foo_1 ; Commit; INFO: 7958 INFO: 7960 INFO: 7962 Thanks, -dvs- From: Pavan Deolasee [mailto:pavan.deola...@gmail.com] Sent: Wednesday, September 05, 2012 1:46 PM To: Sahagian, David Cc: pgsql-general@postgresql.org Subject: Re: [GENERAL] values from txid_current() On Wed, Sep 5, 2012 at 10:53 PM, Sahagian, David <david.sahag...@emc.com<mailto:david.sahag...@emc.com>> wrote: Why are the Messages displayed by my pgAdmin sql window like this . . .

The only way I can see you get those messages is when ALTER TABLE for tables MyCoolTable_2 and MyCoolTable_4 (and possibly others too) are failing for some reason. Thanks, Pavan
