Nothing special, dump + reload. The table in question is tiny - 280 kB, 859 rows.

 
Maybe table-bloat? Filip, check if autovacuum runs properly.


Yes, it does. Just to be sure I ran VACUUM FULL, ANALZYE and REINDEX on all tables and indexes - no change :-(

Any other ideas (before drawing on heavy tools like strace)?


Does it make sense to ask on postgis-users list?


​Thanks,
