It's hard to say without knowing more about the queries you are doing. (If, however, you are asking if there are connection pooling facilities available, the answer currently is no.)
It sounds like you are doing row-bases querying. If so, it may be possible for you to use "union" clauses to combine your queries into one. This should work if your data types are all the same.
For example, you might do something like this:
select id, value from table1
select id, value from table2
