[SL] Change SL from /var/lib/pgsql/data to /sql-old/data

[ATM L. <atm...@km...>]

I want to change SL from /var/lib/pgsql/data to /sql-old/data

Can anyone tell me where this file is?
I cannot seem to find the .conf where this info is held?

Even if it was very temporary so I can get in, backup my data, and then
import it to the working file.

Thanks
