gdb debugging with postgres
hi ,
I am trying to attach a postgres process to gdb, Since I am using only 1
client , I am using the script give by Tom Lane posted in the mailing list.
/messages/by-id/bd6a35510707221030p694cd515kfeb529078557ba42@mail.gmail.com
I started running the client by following command *psql test *where test is
my database.
But When I am running that script I am getting two client processes.
ravi 13368 13366 0 15:14 ? 00:00:00 postgres: checkpointer
process
ravi 13379 13366 0 15:14 ? 00:00:00 postgres: ravi test [local]
idle
Could any one tell me what is checkpointer process and is there any way of
running the script without that process.
Thank you,
K.Ravikiran

You realize that's from 2007?
But When I am running that script I am getting two client processes.
ravi 13368 13366 0 15:14 ? 00:00:00 postgres: checkpointer
process
ravi 13379 13366 0 15:14 ? 00:00:00 postgres: ravi test [local]
idle
There wasn't any checkpointer back in 2007. These days the filter step
of my script looks like
grep -v -e 'grep postgres:' -e 'postgres: stats' -e 'postgres: writer' -e 'p
ostgres: wal writer' -e 'postgres: checkpointer' -e 'postgres: archiver' -e 'pos
tgres: logger' -e 'postgres: autovacuum' | \
In any case you could (and should) have just done "attach 13379" to get
control of the process you wanted. The "ps | grep" dance is just an
aid, not something that is guaranteed to work every time.
