As part of our development, one of our programmers created a new database
type, plus operators and functions to go with it. One of the things he did
was this:
CREATE OPERATOR testbit ( leftarg = bitset, rightarg = int4, procedure = testbit, commutator = testbit
);
Notice that this is an ILLEGAL type - the name of the type (from docs) must
only contain these characters:
+ - * / < > = ~ ! @ # % ^ & | ` ? $
However, PostgreSQL 7.0.3 went right ahead and created the operator anyway!!
Now we have a big problem, as the DROP OPERATOR command cannot delete the
illegally named operator.
eg:
usa=# drop operator testbit (bitset, int4);
ERROR: parser: parse error at or near "testbit "
usa=# drop operator 'testbit ' (bitset, int4);
ERROR: parser: parse error at or near "'"
usa=# drop operator "testbit " (bitset, int4);
ERROR: parser: parse error at or near """
We can't delete it!!! I also assume that it was a bug that it could even be
created in the first place...
