not just C, so that ISCACHABLE attribute can be specified for user-defined

functions. One problem that I have encountered with the function
manager is that it does not allow the user to define type conversion
functions that convert between user types. For instance if mytype1,
mytype2, and mytype3 are three Postgresql user types, and if I wish to
define Postgresql conversion functions like
I run into problems, because the Postgresql dynamic loader would look
for a single link symbol, mytype3, for both pieces of object code. If
I just change the name of one of the Postgresql functions (to make the
symbols distinct), the automatic type conversion that Postgresql uses,
for example, when matching operators to arguments no longer finds the
type conversion function.
The solution that I propose, and have implemented in the attatched
patch extends the CREATE FUNCTION syntax as follows. In the first case
above I use the link symbol mytype2_to_mytype3 for the link object
that implements the first conversion function, and define the
Postgresql operator with the following syntax
The patch includes changes to the parser to include the altered
syntax, changes to the ProcedureStmt node in nodes/parsenodes.h,
changes to commands/define.c to handle the extra information in the AS
clause, and changes to utils/fmgr/dfmgr.c that alter the way that the
dynamic loader figures out what link symbol to use. I store the
string for the link symbol in the prosrc text attribute of the pg_proc
table which is currently unused in rows that reference dynamically
loaded
functions.

now that sequence names are properly quoted for field defaults, mixed
case sequence names are generated. These are properly quoted in the
CREATE SEQUENCE lines, but not in the SELECT nextval lines, as per
below:
CREATE SEQUENCE "Teams_TeamID_seq" start 10 increment 1 maxvalue
2147483647 minvalue 1 cache 1 ;
SELECT nextval ('Teams_TeamID_seq');
This needs to be:
SELECT nextval ('"Teams_TeamID_seq"');

the query string to handle any length, I discovered that under certain
conditions, psql will core dump when handling long strings. Thus, the
patch. It was caused by a buffer overrun, probably not noticeable in a lot
of cases, but pretty noticeable in mine.
Problem was caused by the fact that the length check is only performed after
the check for a ; to get the end of the query and execute.

1. check whether the program is being executed in $PGDATA/.. This is
necessary if the data tree is not in the standard place, as is the
case with the Debian distribution (because of Debian policy).
2. give a clearer error message if the dumped data structure fails to
be loaded.

they were confusing because the large object tables themselves are not
shown. (Besides, if you've got hundreds or thousands of large objects,
you really don't want to see 'em at all.)
Also, suppress all indexes from the \z ACL listing, since indexes have
no meaningful protection information.
