That depends on your shell: .profile for sh, .bash_profile for bash, and
so on.

No, PGDATA in the environment should override the wrapper.

Best to create a testing script to set up the environment.  Call it
psql721 and make sure it is in your path:

    #!/bin/sh
    PGDATA=/usr/local/pgsql/data
    PGPORT=6543
    PGHOST=
    PGLIB=/usr/local/pgs1ql/lib
    PATH=/usr/local/pgsql/bin:$PATH
    LD_LIBRARY_PATH=$PGLIB:$LD_LIBRARY_PATH
    export PGDATA PGPORT PGHOST PGLIB PATH LD_LIBRARY_PATH
    psql $@
