PID of Pgpool-II child process.
See pcp_common_options.
Here is an example output:
$ pcp_proc_info -p 11001
test t-ishii 2018-05-09 11:10:16 2018-05-09 11:10:40 3 0 1 4157 1
test t-ishii 2018-05-09 11:10:16 2018-05-09 11:10:40 3 0 1 4158 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.
The --verbose option can help understand the output. For example:
$ pcp_proc_info -p 11001 --verbose
