Hi:
I run a cron job every day to dump all the tables in my 7.4 Postgres
database. For one of the tables (sample) the command returns this error:
-bash-2.05b$ /usr/local/pgsql/bin/pg_dump -Fc -t sample heos -f
/home/bu/5/sample.dump
pg_dump: socket not open
pg_dump: SQL command to dump the contents of table "sample" failed:
PQendcopy() failed.
pg_dump: Error message from server: socket not open
pg_dump: The command was: COPY public.sample (field1, field2, field3,
field4, field5) TO stdout;
This is what the log shows:
-bash-2.05b$ more /usr/local/pgsql/logfile
LOG: database system was shut down at 2005-09-23 13:43:16 CEST
LOG: checkpoint record is at 122/E90B52AC

repeat your command.

LOG: database system was not properly shut down; automatic recovery in
progress
LOG: record with zero length at 122/E90C3D78
LOG: redo is not required
LOG: database system is ready
This happens every day consistently. The table is quite big, about 1
million tuples and it is vacuumed.
Any help would be appreciated.
Cheers, Ruben.
