Sets a minimum statement execution time (in milliseconds)
- above which a statement will be logged. All SQL statements
- that run longer than the time specified will be logged together
- with their actual duration. Setting this to zero (the default)
- disables time-based logging. For example, if you set it
- to <literal>250</literal> then all SQL statements that run longer
- than 250ms will be logged. Enabling this
- option can be useful in tracking down unoptimized queries in
- your applications.
- Only superusers can increase this or set it to zero if this option
- is set to non-zero by the administrator.
