SQL problems using Postgres

After installing WikiMacroCounter (happens on other parts of Trac as well), I get the following error:

ERROR: current transaction is aborted, commands ignored until end of transaction block

SELECT filename,description,size,time,author,ipnr FROM attachment WHERE type='wiki' AND id='WikiStart' ORDER BY time
