pgactivity is a simple Go program that prints activity within a
Postgres database. It queries the pg_stat_activity view on an
interval (defaulting to every second).
Usage is simple:
$ pgactivity
Configure it by setting libpq environment variables. See the
documentation
for all possible values. Typically you'll want to set PGHOST,
PGUSER and PGPASSWORD:
$ PGHOST=mydatabase.example.com PGUSER=dbuser PGPASSWORD=wolf pgactivity
A timestamp is printed before each result set is printed.
