Re: Howto: Using PITR recovery for standby replication

Alvaro,

I am a newbie, so I essentially invoked pg_dump from with pgAdmin3, with the defaults (including large objects).
This is the command being issued:

.C:\Program Files\PostgreSQL\8.1\bin\pg_dump.exe -i -h 172.20.0.32 -p 5432 -U postgres -F c -b -v -f "C:\Documents and Settings\administrator.MS\testbk.backup" events

What I assumed was happening (and I may have very well been wrong) was that I was getting a consistent backup of the object at the time that it was processed, but not the database as a whole.

How are you creating the dumps of the sequence and the table? If you do
both separately (as in two pg_dump invocations with a -t switch each),
that could explain your problem. This shouldn't really happen however,
because the sequence dump should be emitted in a dump of the table, if
the field is really of SERIAL or BIGSERIAL type. However I don't see
any other way which would make the sequence go out of sync.
