Re: dropped columns and ms access

Still having the same problems with 7.03.02.09 , but the deleted columns may
turn out to be unrelated.

I can load Access, and successfully run forms designed with linked tables,
or open the tables in datasheet mode without error.

The Access mdb containing the linked tables can be left loaded, I can come
back after a period of time, try and open the linked tables in question and
get the previous errors.

Relinking, deleting and recreating links, or closing and reopening the
Access mdb doesn't clear the error.

Closing and reloading Access clears the errors each and every time.

postmaster.log shows some errors that seem to appear once for each failed
attempt to link to a table:

ERROR:  relation "msysconf" does not exist (This can be ignored)
ERROR:  invalid input syntax for type bigint: ""
ERROR:  invalid input syntax for type bigint: ""
ERROR:  invalid input syntax for type bigint: ""
ERROR:  invalid input syntax for type bigint: ""
ERROR:  invalid input syntax for type bigint: ""


The space between the double quotes contains an up arrow when viewed from a
cygwin bash prompt, and a tiny square when viewed in MS Word.



Most of the tables have an int8 field that set up to function like an Access
autonumber or SQLServer ident field, using a sequence, with default value of
nextval('sequence_name').  Access doesn't have a native int8 data type,
although Access projects can use int8 (bigint for SQLServer) data types with
SQLServer tables.



The ODBC driver is set to use row versioning, and all timestamp fields are
timestamp(0) per recommendations for Access. The errors occur whether int8
is configured for default or numeric.



I'm going to change the int8 columns to int4 columns and see if the problem
still occurs.
