Folks,
Perhaps I've misunderstood this, but in PostgreSQL 8.3.5, I get
disparate results from ~ and SIMILAR TO. For example:
This gives an unexpected result:
davidfet...@davidfetter=# SELECT 'abc' SIMILAR TO '^[a]';
?column?
----------
f
(1 row)
This one is what I expected.
davidfet...@davidfetter=# SELECT 'abc' ~ '^[a]';
?column?
----------
t
(1 row)
Did I misunderstand what SIMILAR TO does, or...?
Well, SIMILAR TO is not the same thing as ~. For example, ^ is not a
special character in its pattern language.
