Re: Why i see several postgres server processes sometimes ?

Peter,

Â

This is normal. Postgres is said to have a multi-process architecture
(which is often contrasted with a multi threaded architecture). The
number of processes isn't very predictable.

you are right, it is normal.

But the number of processes is quite predictable:Â

on default PostgreSQL starts up with 5 processes:

one background-writer

one postmaster who masters the startup of additional progresses

one autovacuum-daemon

two processes which I have not leveled up enough to know what they are doing

Â

And thenÂthere is one additional process for every client connection.Â
