No, it certainly should not. Anyone who's admin'd an Oracle installation will tell you what a PITA it is that Oracle keels over and dies when you exceed the fixed log space allocation. The real question here is why the log space isn't getting recycled in a timely fashion. > Postgres.log: > Jan 8 20:15:52 mybox postgres[8037]: [73] LOG: recycled transaction > log file 00001AB100000060 > all other recycling transaction log ... > Jan 8 20:15:52 mybox postgres[8037]: [74] LOG: removing transaction > log file 00001AB100000061 > all other removing transaction log ... > Jan 8 20:17:27 mybox postgres[8213]: [13] LOG: recycled transaction > log file 00001AB2000000A3 > all other recycling transaction log ... > Jan 8 20:17:42 mybox postgres[8213]: [74] LOG: removing transaction > log file 00001AB200000077 > all other removing transaction log ... > Jan 8 20:25:33 mybox postgres[1602]: [13] PANIC: ZeroFill failed to > write /my/pg_xlog/xlogtemp.1602: No space left on device > Jan 8 20:25:35 mybox postgres[8213]: [163] LOG: removing transaction > log file 00001AB2000000EC > Jan 8 20:25:35 mybox postgres[1602]: [14-1] LOG: statement: COPY > table1 (domain, domain_id, customer_id, action_unspecified, > action_unknown, > Jan 8 20:25:35 mybox postgres[8213]: [164] LOG: removing transaction > log file 00001AB2000000ED > Jan 8 20:25:35 mybox postgres[8213]: [165] LOG: removing transaction > log file 00001AB2000000EE > Jan 8 20:25:35 mybox postgres[1602]: [14-2] action_none, action_deny, > action_fail, action_strip, action_tag, action_quarantine, action_clean, > action_copy, action_allow, Hmm. You seem to have removed all the evidence about the interesting question, which is what process 8213 (which was evidently doing a checkpoint) was doing between 20:17:42 and 20:25:35. Also, what postgresql.conf parameters are you using? The mix of "removing" and "recycling" operations seems a bit odd. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
