Hi, I have a Postgres server that has more than 500MB ( shared_buffers = 64000) and looking at TOP command, I couldn't understand why appears some process with 536m and other with 23m. What's the difference between? Wouldn't be all process with 536m, including client connections, but not allocating all this memory, just server process? PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4039 postgres 16 0 537m 13m 536m S 0.0 0.7 0:01.53 postmaster 4040 postgres 16 0 25572 3356 23m S 0.0 0.2 0:00.14 postmaster 4042 postgres 15 0 537m 400m 536m S 0.0 20.0 0:01.63 postmaster 4043 postgres 16 0 25568 3424 23m S 0.0 0.2 0:00.01 postmaster 4044 postgres 16 0 26572 4396 23m S 0.0 0.2 0:01.85 postmaster 4045 postgres 15 0 25848 3584 23m S 0.0 0.2 0:00.96 postmaster Thanks in advance for you help.
