Most query conversion should be trivial, but remember that MS Access
tends to not care about what case your field names are, whereas
PostgreSQL gets pissy if you create a field called SomeCapName and then
try to 'SELECT SomeCapName ...'. You need to 'SELECT "SomeCapName" ...'
instead - or better yet, make sure the converted field names are all
lower case! This goes for other relation names too (tables, etc.)
Do remember, though, that you can phrase crosstab queries in MS Access
(using PIVOT, etc) but you can't do this in PostgreSQL (yet? :). You'd
need to write some form of external program to handle this sort of thing
for you on a query-by-query basis, if you use them in your Access DB.

MS Access has a QBE (Query-By-Example) grid which is displayed by
default when you open the query definition, but you can flip over into
SQL view very easily (it's on the toolbar). The SQL is reasonably
standard stuff.
If you have problems with specific queries, why not post them here?
Hope this helps.
