When using pg_load, you may get an error like the following:
unrecognized configuration parameter "row_security" Command was: SET row_security = off; WARNING: errors ignored on restore: 546
This is an indication that you are using the 9.5 pg_dump/pg_load against an earlier database.
To provide this:
echo $PATH
/E/Program Files/PostgreSQL/9.5/bin
To fix this, you’ll need to change the PATH to include the correct Postgres version.
