PostgreSQL version: 7.4.6
Operating system: RHEL WS 4.0
Description: Unable to insert datetime with fractional seconds in
postgreSQL database using ODBC api
Details:

Hi,

Cause :
Unable to insert datetime with fractional seconds in postgreSQL database
(using timestamp escape sequence).

Environment : RHEL WS 4.0
ODBC DM : libiodbc-3.52.1.tar

1) Table is created using the following statement.
create table product(solddt timestamp);

2) inserted one record using the following statment.
insert into product values('1986-01-12 05:22:10:82375'). The timestamp
values is inserted successfully without any issue. I confirmed that the
timestamp datatype is working without any problem.

3) I have tried to insert using the following C-sample program. In this
sample, I am using ODBC escape sequences to insert TIMESTAMP value.

for example:- "{ts '1986-01-12 05:22:10'}")

4) When executing the C-sample program, I am getting the following error
message in the ODBC log.

Error Message in the ODBC log:-
Error while executing the query (non-fatal);
