PostgreSQL provides various statistics which includes information about
tables, indexes, functions and other database objects and their usage.
Moreover, statistics has detailed information about connections, current
queries and database operations (INSERT/DELETE/UPDATE). But most of this
statistics are provided as permanently incremented counters. The pgcenter
provides convenient interface to this statistics and allow viewing statistics
changes in time interval, e.g. per second. The pgcenter provides fast access
for database management task, such as editing configuration files, reloading
services, viewing log files and canceling or terminating database backends
(by pid or using state mask). However if need execute some specific
operations, pgcenter can start psql session for this purposes.
