Actually, in the log file I also see some messages about has_seq_search:
КОМАНДА: CREATE DATABASE "contrib_regression" TEMPLATE=template0
NOTICE: database "contrib_regression" does not exist, skipping
ERROR: too many active hash_seq_search scans
ERROR: too many active hash_seq_search scans
ERROR: too many active hash_seq_search scans
ERROR: too many active hash_seq_search scans
ERROR: could not fsync segment 0 of relation 1663/16384/2617: No such file or directory
ERROR: checkpoint request failed
I also tried to turn off asserting for dynahash.c, but it didn't help...
regards, Sergey
