PostgreSQL Conversion Function

Notes

CAST

PostgreSQL does not preserve trailing spaces when casting CHARs to VARCHARs, so results may differ when a federated data source or TDV is set to honor trailing spaces.

PostgreSQL data types have the following restrictions for the CAST function:

• Maximum CHAR length is 2000.
• Maximum VARCHAR length is 4000.
• Maximum numeric precision (p) is 38.
• Maximum numeric scale (s) is 38.
