PostgreSQL to TDV Data Types

The table below shows the mapping from PostgreSQL data types to TDV data types.

PostgreSQL data conversion and comparison have these traits:

•

Interval years converted to months result in a TDV data type of VARCHAR.

•

Interval days converted to seconds result in a TDV data type of VARCHAR.

•

Timestamps with a time zone or a local time zone result in a TDV data type of TIMESTAMP.

•

While PostgreSQL honors trailing spaces in general, it ignores them when comparing CHARs. When TDV is set to honor trailing spaces, a filter on a CHAR column might return different results when executed in PostgreSQL vs. TDV.
