In the core dml:
PostgreSQL connections now use advanced options to reduce connection overhead.
These options are not compatible with some connection poolers. The
dbhandlesoptions parameter has been added to allow the database to configure
the required defaults.
This item adds a setting to the logstore_database plugin to let you set the
same flag for your destination database - without it you won't be able to ship
logs to a postgresql database with a pgbouncer frontend.
