I have tried to convert an application from SQLite to Postgresql and I have found two differences:
(1): q = some query like db.table.field<3 b = some boolean like a<3 db(q & b) SQLite needs to convert b to '0' or '1', Postgresql to 'FALSE' or 'TRUE' (2): orderby generates some difficult error messages. I have found the following solution SQLite db(db.table.field==x).select(orderby=db.table.field2, groupby=db.table.field2) Postgresql: db(db.table.field==x).select(orderby=db.table.field2, distinct=db.table.field2) Does somebody has similar experiences?
