Hello, This is a Debian problem that has caused a problem starting Postgres. So, I'm posting it here in the hope that somebody has experienced it previously and can assist me in fixing it. Yesterday, it started up as per normal and first command issued via JDBC driver was run:- 2016-05-04 10:39:39 AESTLOG: MultiXact member wraparound protections are now enabled 2016-05-04 10:39:39 AESTLOG: database system is ready to accept connections 2016-05-04 10:39:39 AESTLOG: autovacuum launcher started 2016-05-04 10:40:00 AESTLOG: duration: 224.906 ms parse <unnamed>: SET extra_float_digits = 3 Today, the following was in the log:- 2016-05-05 03:44:53 AESTLOG: test message did not get through on socket for statistics collector 2016-05-05 03:44:53 AESTLOG: disabling statistics collector for lack of working socket 2016-05-05 03:44:53 AESTWARNING: autovacuum not started because of misconfiguration 2016-05-05 03:44:53 AESTHINT: Enable the "track_counts" option. 2016-05-05 03:44:53 AESTLOG: database system was shut down at 2016-05- 04 11:56:37 AEST 2016-05-05 03:44:54 AESTLOG: MultiXact member wraparound protections are now enabled 2016-05-05 03:44:54 AESTLOG: database system is ready to accept connections 2016-05-05 03:58:29 AESTLOG: duration: 787.241 ms statement: select count(*) from boiler_plate; Relative section of conf file unchanged for months:- # - Query/Index Statistics Collector - #track_activities = on track_counts = on #track_io_timing = off #track_functions = none # none, pl, all #track_activity_query_size = 1024 # (change requires restart) stats_temp_directory = 'pg_stat_tmp' # - Statistics Monitoring - #log_parser_stats = off #log_planner_stats = off #log_executor_stats = off #log_statement_stats = off I can connect via psql and issue queries without any problems. Trying to connect via JDBC fails. Trying to connect by an application fails. I use synaptic for package management. Yesterday I was running short on space and removed some packages described as *obsolete* by synaptic. My guess is that a dependency chain is incorrect and a certain package is not in fact obsolete. For some reason the synaptic history log only shows tzdata-java as being removed but in fact several libraries and other packages were permanently removed. The dpkg logs only show installation details. I don't know why synaptic failed to record the removals in its history logs as if it had, then I could trawl thru the logs and restore the missing packages. The apt logs do not list removals either. Versions:- Java JDK version 1.8.0_91 Linux [ 4.5.0-1-amd64 ] JDBC 9.4-1208 Postgres psql (9.5.2) libpq5_9.5.2-1_amd64.deb Any assistance appreciated.
