bizarre... Its been turned off for a while, but from memory the autovacuum
process was causing the table it was running on to be locked  - I assumed
this was an equivalent to VACUUM FULL - causing all other connections to
wait until it had finished. Could this happen another way, i thought the
other vacuum options acted passively... I'll turn it back on and see what
happens...
