Hi Respected Team

By default proc() does not detach tables concurrently. How do we implement
tables detach concurrently without blocking running sessions in prod.
why this is very critical to implement for pg_partman.
if this is not available yet on 5.1.0 then when can i expect to get it
if already there then please let me know the implementation of detaching
tables concurrently
Any best way to implement the same please with out concurrently how do we
ensure data integrity and consistency

Regards
Durga Mahesh

Fwd: Regarding tables detach concurrently with run_maintenance_proc()

Hi Respected Team

with pg_partman By default proc() does not detach tables concurrently. How
do we implement tables detach concurrently without blocking other sessions
Here queries not using date column to detach tables with
run_maintenance_proc() which is not using concurrently based on the
retention policy which leads to scan all available child tables hence need
to trigger this proc with concurrently option to avoid blocking other child
tables beyond rentention policy while running statements on them

Do we have any other alternative rather than using pg_partman()?

your response is valuable

Durga Mahesh

You might have more success by filing pg_partman issues at
https://github.com/pgpartman/pg_partman/issues

Well you can just run the same commands manually that pg_partman would
run.

Hi
You might have more success by filing pg_partman issues at

My intention is to have any other extension other than pg_partman to
manage table partitions manually

Hi ,

You can consider the pg_pathman extension.
