Hi,
I've had a weird problem in a production system. The customer had
installed a new server with our software on it. The software installs a
Postgres database schema that includes a number of triggers. The
triggers perform inserts into an additional table.
In this installation, from what I

precise major version in front of me) have N^2 behavior on the number of

Hi!
Will wal_keep_segments keep segments also if named replication slot is
lot used ?
Well if you are using a replication slot there is no point in using
wal_keep_segments. Slots where created in, part at least, so you did not
have to guess at a wal_keep_segments number.
I dont use slot.

Okay I'll bite.
Comparing Postgres with Oracle is a bit like comparing a rubber duck you
might buy your three year old, with a 30 ton super tanker.
Do they both float? Yeah, but that's about the only similarity.
The rubber duck barely tells you how and why it floats, but the super
