Excerpts from Josh's message On Sun, Aug 7, 2011 at 2:36 AM:
could we figure out what that limit should be based on max_locks_per_transaction?
It would be nice to implement via "-l max" instead of making users do it manually or something like this "-l $(grep "max_locks_per_transaction.*=" postgresql.conf | perl -p -e 's/#.*//g;s/^.*?([0-9]+).*?$/$1/g' | grep . |head -1 )".
For this patch I just want to enable the limit functionality, leaving higher level options like max to the user for now.
handle deleting all the ophan LOs in several transactions for the user automatically?
I addressed this option before and basically said it is an undesirable alternative because It is a less flexible option that is easily implemented in a shell script.
Again it would be a welcome extra option but it can be left to the user for now.
