Hi! I was searching for a command like pg_dumpall but with the
difference that I don’t want a single file for all databases, i would
like to have a file for each one.
I couldn’t fins such command, so the only option I see is to write a
shell script with a loop for all the DBs. The problem is that I’m unable
to find the way to obtain the DBs’ names in a shell script. Can someone
help me with this?
Best regards and thank you all for your time.
psql -ltA
a little read, cut, awk, perl, etc action and you should be good.

Aha, yes, I should really look at the psql options more.
You could extend that to exclude templates and the postrgres database and database attributes:
psql -ltA | cut -d "|" -f 1 | grep -v "\( template0 \| template1 \| postgres \| : \)"
And using Scott's loop:
for line in `psql -lt | cut -d "|" -f 1 | grep -v "\( template0 \| template1 \| postgres \| : \)" | head -n -1 `; do pg_dump -f /home/backups/`date +\%Y\%m\%d`/"$line".sql; done
Or adapt it to put it into dated directories. Anyone got a tidier way? :S
