Regarding conversion of SQL_TSI_DAY operator for Datetimeadd function in ODBC driver


Platform / Version info:
Postgres 11.4
psqlODBC_x64 v 11.01.0000

I'm a developer working with PowerQuery / ODBC and I'm running into the following issue.

I'm developing a custom connector which is utilizing this driver. I've attached the logs as requested when making a bug report. It looks like the SQL_TSI_DAY operator is being "interpreted" by the driver as a column reference rather than making the necessary conversion to the correct datetimeadd "interval" .
I'm attaching the connector file - ODBCPostgresDirect simply because it contains all the flags that I'm setting for SQLCapabilities, ODBC function overrides etc.
Any input on this would be helpful.
