Hi All,

I can't confirm this against the current latest CVS as my
local tree has undergone some changes, but we seem to have
a problem with "pg_dump" and user defined types.

If I create a type like so:-

CREATE FUNCTION sotime_in (opaque ) RETURNS opaque AS
'/usr/local/pgsql/shlibs/obj/sotimes.so' LANGUAGE 'C';

CREATE FUNCTION sotime_out (opaque ) RETURNS opaque AS
'/usr/local/pgsql/shlibs/obj/sotimes.so' LANGUAGE 'C';

CREATE TYPE sotime ( internallength = 2, externallength = 5,
input = sotime_in, output = sotime_out, send = sotime_out,
receive = sotime_in, default = '-',passedbyvalue);

pg_dump gives me back :-

CREATE TYPE sotime ( internallength = 2, externallength = 5,
input = sotime_in_18272, output = sotime_out_18304, send = sotime_out_18304,
receive = sotime_in_18272, default = '-',passedbyvalue);

CREATE TYPE _sotime ( internallength = -1, externallength = -1,
input = array_in_750, output = array_out_751, send = array_out_751,
receive = array_in_750, default = '-');
.
<table creates>
.
CREATE FUNCTION sotime_in (opaque ) RETURNS opaque AS
'/usr/local/pgsql/shlibs/obj/sotimes.so' LANGUAGE 'C';
CREATE FUNCTION sotime_out (opaque ) RETURNS opaque AS
'/usr/local/pgsql/shlibs/obj/sotimes.so' LANGUAGE 'C';


Looks like the FUNCTION creates are OK but the TYPE creation
is a little confused.

I remember some discussion about name mangling for the functions
but it looks like pg_dump can't cope with this.

Another thing I can't understand is pg_dump dumping the _sotime
type, which seems to be created automatically when I create
the sotime type.

Needless to say, I can't dump/restore a database with user defined
types at all.

Keith.

BTW: I was looking as pg_dump'ing VIEWS.
