Thank you.
BTW, if you interested in this tool, I may send you fresh versions or place it on the
web.
Maybe you will or somebody help me with one problem ? Do you know PL/pgSQL and how to
create new type in Postgres ?
The problem is that I can't use new type constructed with CREATE TYPE if transform
functions written on PL/pgSQL.
Because PL/pgSQL doesn't support type "opaque", or I do something wrong. The same
function on PL/pgSQL with
input argtype "text" or "int2" works fine, but when I simply change argtype to
"opaque", I get "compilation error near line 0".
Source is below.
Thanks,
Max Rudensky.
