So process 66017 and 66014 are blocking each because they are
running the exact same queries. The interesting part is the process
with the lower pid is starting later then the none with the higher pid.
Locking is obvious. But why deadlock? There is just single row, and it
shouldn't be able to deadlock on it?!
Well both queries are doing SELECT .. FOR UPDATE as well as UPDATE. From
what I see there are four queries contending for the same row.
So what exactly is 'importer' and what does it do?
Some software written by some guy. Runs lots of queries, but the only
problem we have is with these transactions.
Also what is this (59303)?
log_line_prefix is '%m %r %p %u %d ' so it's port number.
So why are different processes running the exact same queries coming in
on different ports?
