The following bug has been logged on the website:
Bug reference: 13620
Logged by: Jürgen Strobel
Email address: juergen+postgresql@strobel.info
PostgreSQL version: 9.4.4
Operating system: Linux, REL6
Description:
Hello,
I frequently use "watch ps xf" to monitor server restarts etc., it's really
a great, simple and effective tool. But there is a minor formatting issue,
which has caused considerable confusion not only for me already.
For example:
postgres$ ps xf
... /usr/pgsql-9.4/bin/postmaster -D /mnt/db/.../data
... \_ postgres: startup process recovering 00000005000004B500000007
... \_ postgres: wal receiver process streaming 4B5/78A2C80
... \_ postgres: wal sender process replication [local] streaming
4B5/78A2C80
>From the last 2 lines I would guess at first glance that those processes are
streaming segment "78" at the moment, while they really are at segment "07".
It should be trivial to zero-pad this id.
Best regards,
Jürgen
