Which ODBC driver are you using?

It looks like no one has gotten round to teaching ours that there is
no more query length limit --- it still has hardwired internal buffer
sizes :-(. But the limit it imposes appears to be 16K not 8K in the
current code. If you are getting 8K then you are probably using a
very old version of the ODBC code, or maybe someone else's driver
entirely.

A quick-hack solution is just to increase MAX_QUERY_SIZE in
src/interfaces/odbc/psqlodbc.h to whatever you need.
