Hi - I seem to be unable to reLOAD a shared library within the session that I LOADed it. I am developing a UDF and my debugging changes do not appear to take until I quit psql and restart. The following code sequence demonstrates the issue
kbmod=# CREATE OR REPLACE FUNCTION hello(TEXT) RETURNS TEXT AS '/Users/acbecker/src/github/kbmod/src/hello.so', 'hello' LANGUAGE C STRICT;
kbmod=# SELECT hello( name ) FROM test; hello
----------------Hello4, XavierHello4, YariHello4, Zack
(3 rows)
### HERE I MODIFY hello.c TO TYPE "Hello5" AND REBUILD hello.so
### DROPPING AND RECREATING THE FUNCTION DOES NOT WORK
kbmod=# DROP FUNCTION hello(TEXT);
kbmod=# CREATE OR REPLACE FUNCTION hello(TEXT) RETURNS TEXT AS '/Users/acbecker/src/github/kbmod/src/hello.so', 'hello' LANGUAGE C STRICT;
kbmod=# SELECT hello( name ) FROM test; hello
---------------Hello4, XavierHello4, YariHello4, Zack
### RELOADING THE SHARED LIBRARY ALSO DOES NOT HELP
kbmod=# LOAD '/Users/acbecker/src/github/kbmod/src/hello.so';
LOAD
kbmod=# SELECT hello( name ) FROM test; hello
----------------Hello4, XavierHello4, YariHello4, Zack
(3 rows)
### HOWEVER, AFTER QUITTING AND RESTARTING, THE CHANGE TAKES
kbmod=# \q
prompt>:/opt/local/lib/postgresql93/bin/psql -U postgres -d kbmod
psql (9.3.5)
Type "help" for help.
kbmod=# SELECT hello( name ) FROM test; hello
----------------Hello5, XavierHello5, YariHello5, Zack
(3 rows)
Hints as to what is going wrong here? I would certainly expect to be able to re-load a shared library while debugging my UDF.
Thanks,
Andy
