The classic output from top (during all other index vacuum):
PID UID PRI NICE SIZE RES STATE WAIT TIME CPU COMMAND
20461 503 14 0 13M 75M sleep semwai 5:27 2.05% postgres
When backend hits the tsearch2 index, SIZE/RES grows until it reachs
1GB, where I got the error.
PID UID PRI NICE SIZE RES STATE WAIT TIME CPU COMMAND
20461 503 -5 0 765M 824M sleep biowai 4:26 33.20% postgres
