Ali Ibrahim 1c6e508ade Cache database version in schema cache ... * The database version will get cached in the schema cache file during the schema cache dump. When the database version check happens, the version will be pulled from the schema cache and thus avoid querying the database for the version. * If the schema cache file doesn't exist, we'll query the database for the version and cache it on the schema cache object. * To facilitate this change, all connection adapters now implement #get_database_version and #database_version. #database_version returns the value from the schema cache. * To take advantage of the cached database version, the database version check will now happen after the schema cache is set on the connection in the connection pool.		2019-04-03 11:10:14 -04:00
