To run Database Designer for PostgreSQL on your non-Windows box under Wine you should use at least:
§Wine 1.0.1
§Winetricks version 20091022.
Database Designer for PostgreSQL uses GDI+ library in the work. To install appropriate files please use the command:
$sh winetricks gdiplus
Since Database Designer for PostgreSQL uses Microsoft Data Access Components for its Universal and MS Access Database Reverse Engineering appropriate redistributable runtime libraries should be installed:
$sh winetricks jet40 mdac28
jet40 - MS Jet 4.0 Service Pack 8
mdac28 - MS MDAC 2.8: Microsoft ODBC drivers, etc.
Database Designer for PostgreSQL will function normally even without these runtime libraries: only Universal and MS Access Database Reverse Engineering functions will be disabled.
After this application already can be used with its full functionality. However, fonts used in Designer appear ridged. To fix this install Microsoft Core Fonts (Arial, Courier, Times etc.), but make sure cabextract utility is present in the system.
$sh winetricks corefonts
