Here is an example output:

$ pcp_proc_info -h localhost -p 9898 -U postgres 3815
postgres_db postgres 1150769932 1150767351 3 0 1 1467 1
postgres_db postgres 1150769932 1150767351 3 0 1 1468 1
    

The result is in the following order:

1. connected database name
2. connected user name
3. process start-up timestamp
4. connection created timestamp
5. protocol major version
6. protocol minor version
7. connection-reuse counter
8. PostgreSQL backend process id
9. 1 if frontend conncted 0 if not

If there is no connection to the backends, nothing will be displayed. If there are multiple connections, one connection's information will be displayed on each line multiple times. Timestamps are displayed in EPOCH format.

The --verbose option can help understand the output. For example:

$ pcp_proc_info --verbose -U postgres 3815
