Hello
it working on my comp
postgres=# select mystr, test_repl(mystr) replaced_strfrom str_table;
mystr | replaced_str
---------------------------+----------------------------------
This road is INDEFLY CLSD | This road is indefinitely closed
That is INDEFLY open | That is indefinitely open
That is a CLSD road | That is a closed road
(3 rows)
I don't see a problem in your code, I am thinking so it's ok.
try to debug code with RAISE NOTICE statement
for a in select * from lookup
loop
RAISE NOTICE 'lookup rec: %', a;
RAISE NOTICE 'ret_var before replace: %', ret_var;
ret_var := replace(ret_var,a.code,a.codeword);
RAISE NOTICE 'ret_var after replace: %', ret_var;
end loop;
return ret_var;
you can ensure using just buildin "replace" function - use
ret_var := pg_catalog.replace(...)

maybe it can help to identify a problem
