You can restrict access on a table-by-table basis using the SQL
GRANT command. For instance, for web access using Apache server
side includes, the user nobody must have the appropriate access. I
allow web users to read a database but not change it, so for any table
a web user might need to read I run the command:
GRANT SELECT ON <table name> TO nobody ;
Of course, for this to work the user 'nobody' must be already a
PostgreSQL user. BTW, the opposite of GRANT is REVOKE, which
you can use to revoke a database privilege for a PostgreSQL user.
