Perhaps on Unix, but I don’t think it is on Windows?
C:> netstat -abo
…
TCP 0.0.0.0:5432 SPNX-1Z2SRV3:0 LISTENING 39060
[postgres.exe]
…
I can see that the “directory structure” has mentions of “postmaster”
[13:50:24.50 C:\postgresql18]
C:> dir/s/b postmaster*
C:\postgresql18\data\postmaster.opts
C:\postgresql18\data\postmaster.pid
C:\postgresql18\include\server\postmaster
C:\postgresql18\include\server\postmaster\postmaster.h
… but on windows, that’s not visible in the pathname of the executable.
[13:52:20.45 C:\postgresql18]
C:> dir/s/b postgres.exe
C:\postgresql18\bin\postgres.exe
Again, only an issue because in a past life, “postmaster” was a different user-id used by a completely different application, so it’s not critical, it’s just misled and sent me down the wrong blind alley.
