Hi,
I have a number of tables with serial columns as a primary key.
I'm looking to add lots of records via copy, but should reset the
serial counters to the appropriate value after this.
Is there a simple way to do this, or do I just update the last_value
column in each seq table to the max(id) from the relevant table.
You shouldn't edit sequence table directly. To set a sequence's value
you should use the setval(seqname, seqval) function like so:
SELECT setval('some_seq', 1000);
