Re: Using psql to insert character codes

Ah, I see.  </mac_over_enthusiasm>  In that case, I would recommend
just making a custom function that handles that for you, maybe:

create function hex2esc(text) returns text as '
select encode(decode($1,''hex''), ''escape'');
' language sql;

Not a whole lot more elegant but shorter.

Best,

Randall
