This package provides the following PostgreSQL modules:
|
|
- auto_explain
|
|
- pg_buffercache
|
|
- pg_stat_statements
|
|
- pgstattuple
|
|
|
|
The "auto_explain" module provides a means for logging execution
|
|
plans of slow statements automatically, without having to run
|
|
EXPLAIN(7) by hand. This is especially helpful for tracking down
|
|
un-optimized queries in large applications.
|
|
|
|
The "pg_buffercache" module provides a means for examining what's
|
|
happening in the shared buffer cache in real time.
|
|
|
|
The "pg_stat_statements" module provides a means for tracking
|
|
execution statistics of all SQL statements executed by a server.
|
|
|
|
The "pgstattuple" module provides various functions to obtain
|
|
tuple-level statistics.
