Resolved Issues The following issues have been resolved in Simba PostgreSQL ODBC Connector 1.5.11.
[PGODBC-1640] When SQLColumns() function is called, the connector returns 0 instead of NULL for NUM_PREC_RADIX and CHAR_OCTET_LENGTH.

The connector computes the value returned for SQL_DESC_OCTET_LENGTH from the IRD (and thus also SQLColAttribute) for character types by using the maximum size of a codepoint, instead of the size of a code unit. For both wide and non-wide types, the column size was previously used directly for non-wide types as the code unit size was assumed to be 1.
