Testing 1.7: Errors with function pldbg_get_target_info(..)

Hi developers! Hi Dave!

Still testing pgAdmin III 1.7.0, rev 6292:6293. Client Win XP, hosts:
Debian Sarge / PG 8.1.8 and Debian Etch / PG 8.2.3 (and looking forward
to the snapshot to come)

I found multiple occurrences of this mysterious error message in my
logs. while testing pgAdmin3 1.7 (with pg 8.1.8 server). A quick google
search has found the string 'pldbg_get_target_info' in pgAdmin source
code...

FEHLER: Funktion pldbg_get_target_info("unknown", "unknown") existiert
nicht
TIPP: ....
ANWEISUNG: SELECT * FROM pldbg_get_target_info('version', 'f');

Translates:
ERROR: Function pldbg_get_target_info("unknown", "unknown") does not exist
HINT: ...
STATEMENT: SELECT * FROM pldbg_get_target_info('version', 'f');

Regards
Erwin
