Is that the complete message? Does anything else show up on your
screen or in the server logs? What statement did you execute that
caused these warnings? What version of PostgreSQL are you using?

What data type is query_table? I ran a test with query_table as a
TEXT column and the code you posted worked in 7.4.6 and 8.0.0rc4.
If query_table is some other type (e.g., OID), then you'll need to
convert it to a string that contains the table name.

Please post a self-contained example: all CREATE and other statements
that somebody could copy and paste into an empty database to reproduce
the problem. Please reduce the problem as much as possible: if a
table has 50 columns then we probably don't need to see them all --
if only one column is relevant then create a test table with just
that one column. That makes it easier for everybody (including you)
to see what's going on.
