ecpg help with 7.3

Hi all,

   To start with we have recently migrated from v7.2.3 to v7.3, and I have
an embedded SQL code (ecpg) that used to work fine with 7.2.3. With the new
7.3 it gives me an error when inserting into a table,
Cannot Insert in table xyz(-400):50 'ERROR: pg_atoi: zero-length string'
my first guess was that there was a zero length string (NULL) being inserted
in the table... but the attributes of the columns in the table are such that
they can accept NULL's too.
Having done this i tested the same data over 7.2.3 and it worked good. Can
somebody help me with this please .....


Thanks and regards
