Repair bug noted by Paul Caskey: neqsel() has been generating a bogus
result, in fact nearly the opposite of what it should, because it
was passing the not-equal operator to eqsel() which would use it to
compare the value against the most common value in the column, and
of course obtain the wrong result therefrom. Must pass the equality
operator to eqsel() instead. Fortunately that's easy to get from

Sometimes when the postgres connection dies it is necessary to

connection (if there is one). These patches ensures that any open
