It also seems possible that you forgot to change the SQL
statement that you used to add the function(s) into the database.
Somewhere, you ran a SQL statement of the form:
create function bool2int(opaque) returns int4
as '/usr/local/pgsql/procs/bool2int.o'
language 'c';
So make sure you change that ".o" to ".so". BTW, this is
true on most Unix flavors, if not all. If you have to pass parameters
to the 'bool2int()' function, then describe them rather than using
the "opaque" description.
