Invalid use of ntid in INSERT INTO command

Hi LouBabe,

I use PostgreSQL and the INSERT INTO just cannot have the ntid defined with 0 (you actually use '' for a %d which is doubly wrong, but that PHP takes care of.) That 0 is taken literally by PostgreSQL and once I inserted a first ticker, it breaks since the second ticker tries to use 0 again.

See attached patch for the fix.

Thank you.
