Description:        ODBC driver. Binding Arrays of Parameters
Details:

Using ODBC, I encountered an error.
I used the ODBC API to insert an array of records.
Example:
unsigned long r = 5;
SQLSetStmtAttr(stmt, SQL_ATTR_PARAM_BIND_TYPE, SQL_PARAM_BIND_BY_COLUMN,
0);
SQLSetStmtAttr(stmt, SQL_ATTR_PARAMSET_SIZE, &r, 0);
….
// Bind the parameters in column-wise fashion.
SQLBindParameter(…)
…
When you run the error occurred.
SQLExecDirect(hstmt, Statement, SQL_NTS);

Errors are detected in the implementation of SQLSetStmtAttr in the ODBC
driver. Coming PGAPI_SetStmtAttr (HSTMT StatementHandle, SQLINTEGER
Attribute, PTR Value, SQLINTEGER StringLength) in pgapi30.c
For SQL_ATTR_PARAMSET_SIZE transformation
SC_get_APDF (stmt) -> paramset_size = CAST_UPTR2 (SQLUINTEGER SQLINTEGER,
Value);
led to the fact that paramset_size not equal to 5 and the number of memory
address that contains the variable r.
