vcenter postgresql
Disclaimer: describes vcenter 6.0 - it may vary for other versions ?
vcenter uses an embedded postgresql installation. Binaries are located in /opt/vmware/vpostgres/current/bin - data and config files are located in /storage/db/vpostgres/
on installation vcenter sets a number of config overrides in <datadir>/postgresql.conf.auto - pay attention to work_mem
and temp_buffers
- they might be set lower than postgresql default values (which is quite silly imho.)
start psql client with /opt/vmware/vpostgres/current/bin/psql -h localhost -U postgres
