[SAC] Trac postgres conversion

[Frank Warmerdam]

Folks,

This evening I completed converted the remaining Trac instances
to use postgres instead of sqlite and put in place backup procedures.
I'll try and document it more completely tomorrow.

Please let me know of any problems experienced.

Best regards,
