Re: Displaying text appears as hex data

Hello Thom,

I sent this accidentally to you directly, here's a copy for the
list as well.

That's understandable and PostgreSQL is doing the right thing, but...

opensips=> SELECT id, time_stamp, callid, traced_user,
convert_from(msg, 'SQL_ASCII'), method FROM sip_trace;
ERROR: function convert_from(text, unknown) does not exist
LINE 1: SELECT id, time_stamp, callid, traced_user, convert_from(msg...
^

The arrow in the last line indicates that 'convert_from' is not
correctly parsed.

Is it because I've not build something in:

src/backend/utils/mb/conversion_procs

I think I built a standard PostgreSQL installation, or?
