PostgreSQL

Managed instance of the PostgreSQL database server.

Components

• PostgreSQL server

Configuration

Managed PostgreSQL instances already have a good basis configuration with reasonable sized memory parameters (for example, shared_buffers, work_mem). Project-specific configuration goes into /etc/postgresql-VERSION/postgresql-local.conf.

Interaction

Service users can use sudo -u postgres -i to access the PostgreSQL super user account to perform administrative commands like createdb and createuser.

Both service users and the postgres DB super user may invoke

sudo /etc/init.d/postgresql-${VERSION} restart

to restart the PostgreSQL server after configuration changes (replace $VERSION with the installed PostgreSQL version).

Monitoring

The default monitoring setup checks that the PostgreSQL server process is running and that it responds to connection attempts to the standard PostgreSQL port.

Miscellaneous

Our PostgreSQL installations have the autoexplain feature enabled by default.
