the log isn't in a column oriented format although you can define a
custom log prefix of things like timestamp, database user, connection
IP, database name, process ID, and those could be treated as columns,
according to whatever seperators you specify as part of your custom log
prefix.
past that, the log is plain text. by default only errors and a few key
system events are logged (startup, shutdown), but you can increase the
amount of logging via the various options in postgresql.conf, including
logging all statements, all connections, etc.
whatever you do, its going to be a lot of plain text parsing, I think if
it was my job, first thing I would do is generate some sample logs and
look at them to see how to proceed.
