Method Sql.pgsql()->getstatistics()

Method getstatistics

final mapping(string:mixed) getstatistics()

Returns

A set of statistics for the current session:

"warnings_dropped" : int	Number of warnings/notices generated by the database but not collected by the application by using error() after the statements that generated them.
"skipped_describe_count" : int	Number of times the driver skipped asking the database to describe the statement parameters because it was already cached. Only available if PG_STATS is compile-time enabled.
"used_prepared_statements" : int	Number of times prepared statements were used from cache instead of reparsing in the current session. Only available if PG_STATS is compile-time enabled.
"current_prepared_statements" : int	Cache size of currently prepared statements.
"current_prepared_statement_hits" : int	Sum of the number hits on statements in the current statement cache.
"prepared_statement_count" : int	Total number of prepared statements generated.
"portals_opened_count" : int	Total number of portals opened, i.e. number of statements issued to the database. Only available if PG_STATS is compile-time enabled.
"bytes_received" : int	Total number of bytes received from the database so far.
"messages_received" : int	Total number of messages received from the database (one SQL-statement requires multiple messages to be exchanged).
"reconnect_count" : int	Number of times the connection to the database has been lost.
"portals_in_flight" : int	Currently still open portals, i.e. running statements.

Note

This function is PostgreSQL-specific, and thus it is not available through the generic SQL-interface.
