Ok - lookint at the pg log, it appears that the server process is seg
faulting :(. This might conceivably be my fault. I have 3 stored
procedures written in C, but they've been on the server for months,
and unless I didn't deploy them correctly originally I don't think
it's them.
I'm thinking I need a core file. I'm guessing I just restart
postgresql from a user whos core file size limit is set to non zero?
