The error you're seeing is the result of a previous error.
Without seeing that earlier error and the query that caused it nobody can tell you what's wrong with your query, because we don't even know which query you're talking about.
Errors in transactions behave like this:
postgres=> BEGIN;
BEGIN
postgres=> SELECT 1; ?column?
----------
1(1 row)
postgres=> SELECT;
ERROR: syntax error at or near ";"
LINE 1: SELECT;
^
postgres=> SELECT 1;
ERROR: current transaction is aborted, commands ignored until end of transaction block
As you can see, there is nothing wrong with the query that causes the error "current transaction is aborted". It is a query before it that threw an error and caused the transaction to be aborted.
The only ways to get out of the aborted transaction is to either roll it back or to commit (which will also roll back).
You can also use SAVEPOINTs between blocks of queries that you don't want to roll back (sub-transactions). With those you can just roll back to an earlier savepoint and continue from there.
You really should read the relevant documentation at: http://www.postgresql.org/docs/8.3/static/tutorial-transactions.html
P.S. Please don't top-post on this list.
P.P.S. And please include the list in your replies (reply all).

Screwing up is an excellent way to attach something to the ceiling.
