I'm not too familiar with PostgreSQL internals, but I wouldn't bet on
that. If the result is a long or long long integer, get_int will return
an error. What does the following call return:

unsigned int attribs;
attribs = dbi_result_get_field_attribs_idx(data, 1);

attribs should contain the size of the integer as explained in dbi/dbi.h
(see the DBI_INTEGER_* definitions).

regards,
Markus
