Another interesting thing abut psql that I noticed when using '$' in
identifiers is this effect:
andrew=# create table ab$cd$ef (ef$cd$ab text);
CREATE TABLE
andrew=# \d ab$cd$ef
Did not find any relation named "ab$cd$ef".
andrew=# \d ab\$cd\$ef Table "public.ab$cd$ef" Column | Type | Modifiers
----------+------+-----------ef$cd$ab | text |
which is perhaps slightly less than intuitive.
