Somehow I have managed to have two tables with duplicate keys.
In both tables, the key is an integer, filled from a sequence.
There is only 1 duplicated entry in each table: in the first
table, there are two ID "1"s, and in the second table there are
two ID "123456"s (the second table entry is linked to the first
table's ID 1).
I noticed this because a pg_dump followed by a psql < dumpfile
will not reload.
I've figured out a fix: a script that cleans the dump file, removing
the two duplicate lines (leaving the original).
But, mostly, I'm wondering how I managed to get in this state,
if it was something I did, or perhaps caused by killing the
postmaster the wrong way (I don't think I ever did this, but
maybe), or a crash.
I did do a brief search, didn't find anything seemingly related to this.
Thanks,
j
