postgresql.conf in macOS Big Sur

Question

I'm on a macOS Big Sur , and struggling to find the config file postgresql.conf

While in /Applications/Postgres.app/Contents/Versions/13 I ran this

➜  13 find . -type f -name "postgresql.conf"
➜  13 
➜  13 
➜  13 pwd
/Applications/Postgres.app/Contents/Versions/13

If I go into share/postgresql/ I see a bunch of sample files, but that is not what I am looking for

I tried to go back further and search there

find . -type f -name "postgresql.*"   


./Contents/Versions/13/share/postgresql/postgresql.conf.sample

I only found the sample file: postgresql.conf.sample

If you know, please help....

Your DB keeps this information for you. Connect to your database and run show commands. Eg

postgres> # show config_file ;
-[ RECORD 1 ]----------------------------------------------------------
config_file | [your directory structure]/postgresql.conf

postgres> # show data_directory ;
-[ RECORD 1 ]--+------------------------------------------
data_directory | [your directory structure]
