I have created a new type and by struggling with the instructions at
http://www.postgresql.org/docs/programmer/xindex.htm (I'm preparing some
corrections) I di everything that I can to set this up fully. I am able
to create a table using my type as the primary key and insert data into
it fine. However, when I try to update or select using a WHERE clause I
get the following.
ERROR: fmgr_info: function 0: cache lookup failed
Here is the SQL to create the type. Any ideas?
--
-- PostgreSQL code for GLACCOUNTs.
--
-- $Id$
--
load '/usr/local/pgsql/modules/glaccount.so';
--
-- Input and output functions and the type itself:
--
create function glaccount_in(opaque)
returns opaque
as '/usr/local/pgsql/modules/glaccount.so'
language 'c';
create function glaccount_out(opaque)
returns opaque
as '/usr/local/pgsql/modules/glaccount.so'
language 'c';
create type glaccount (
internallength = 16,
externallength = 13,
input = glaccount_in,
output = glaccount_out
);
--
-- Some extra functions
--
create function glaccount_major(glaccount)
returns int
as '/usr/local/pgsql/modules/glaccount.so'
language 'c';
create function glaccount_minor(glaccount)
returns int
as '/usr/local/pgsql/modules/glaccount.so'
language 'c';
create function glaccount_cmp(glaccount, glaccount)
returns int
as '/usr/local/pgsql/modules/glaccount.so'
language 'c';
--
-- The various boolean tests:
--
create function glaccount_eq(glaccount, glaccount)
returns bool
as '/usr/local/pgsql/modules/glaccount.so'
language 'c';
create function glaccount_ne(glaccount, glaccount)
returns bool
as '/usr/local/pgsql/modules/glaccount.so'
language 'c';
create function glaccount_lt(glaccount, glaccount)
returns bool
as '/usr/local/pgsql/modules/glaccount.so'
language 'c';
create function glaccount_gt(glaccount, glaccount)
returns bool
as '/usr/local/pgsql/modules/glaccount.so'
language 'c';
create function glaccount_le(glaccount, glaccount)
returns bool
as '/usr/local/pgsql/modules/glaccount.so'
language 'c';
create function glaccount_ge(glaccount, glaccount)
returns bool
as '/usr/local/pgsql/modules/glaccount.so'
language 'c';

-- Now the operators. Note how some of the parameters to some
-- of the 'create operator' commands are commented out. This
-- is because they reference as yet undefined operators, and
