Bug: Error in pg_get_userbyid when connecting to database (pgAdmin III 1.8 beta 3)

[Sebastiaan van Stijn <sebastiaan(at)johanvanstijn(dot)nl>]

I just downloaded and installed pgAdmin III 1.8 beta 3, however, when  
I connect to a database, I get the following error:


ERROR: Syntax error at or near "pg_get_userbyid"
LINE 1: ...T ts.oid, spcname, spclocation, '' AS description  
pg_get_use...


pgAdmin version:
1.8.0 Beta 3 (Aug 10 2007, rev: 6544:6546)

I'm running pgAdmin on;

- iMac 2.16 GHz Intel Core 2 Duo, 2Gb Ram
- Mac OS X 10.4.10
