To reproduce, go to SQL window in console and run
CREATE TABLE testTbl (id INT);
The regular expression seems to capture the table name as testTbl and the track_table request is to track the table testTbl. But postgres converts identifiers to lower case unless they are quoted. This results in a track_table error.
This will not work even if quoted.
CREATE TABLE "testTbl" (id INT);
In this case, the regular expression captures the table name as "testTbl" but it should be testTbl.
