URL NameSQLExecute-fails-to-detect-duplicate-index-with-PostgreSQL-ODBC-driver

EnvironmentProduct: Connect for ODBC PostgreSQL driver
Version: 7.16.0233
OS: all supported platforms
Database: PostgreSQL
Application: all supported applications
Question/Problem Description
SQLExecute fails to detect duplicate index with PostgreSQL ODBC driver when statement is prepared then executed.
Steps to Reproduce
Clarifying Information
1. Create the following table:

CREATE TABLE "J33"  (ITEM_NAME VARCHAR(1024),   ITEM_ID INTEGER NOT NULL,  ITEM_PRICE DOUBLE PRECISION,  CONSTRAINT pk_item_ID33 PRIMARY KEY ( ITEM_ID ))

2. Create the following table by calling SQLPrepare/SQLExecute:

CREATE TABLE "J333"  (ITEM_NAME VARCHAR(1024),   ITEM_ID INTEGER NOT NULL,  ITEM_PRICE DOUBLE PRECISION,  CONSTRAINT pk_item_ID33 PRIMARY KEY ( ITEM_ID ))

SQLPrepare:
In:    StatementHandle = 0x045CDB18, 
StatementText = "CREATE TABLE "J333" (ITEM_NAME VARCHAR(10...", TextLength = 161
Return:    SQL_SUCCESS=0
SQLExecute:
In:    StatementHandle = 0x045CDB18
Return:    SQL_SUCCESS=0

SUCCESS is returned while an error should be returned that the index already exists.
Error Message[DataDirect][ODBC PostgreSQL Wire Protocol driver][PostgreSQL]NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "pk_item_id33" for table "JFL_LEAK333"(File indexcmds.c; Line 578; Routine DefineIndex; )
Defect Number
Enhancement Number
Cause
Resolution
This issue is no longer seen when installing the latest hot fix (7.16.0251).
Refer to "Connect and Connect64 for ODBC hot fix download and install instructions" for instructions on how to download and install the hot fix.
Workaround
SQL_ERROR is returned correctly when calling SQLExecDirect instead of SQLPrepare/SQLExecute:

SQLExecDirect:
In:    hstmt = 0x045CDB18, 
szSqlStr = "CREATE TABLE "J333" (ITEM_NAME VARCHAR(1024), ...", cbSqlStr = -3
Return:    SQL_ERROR=-1
stmt:    szSqlState = "42S01", *pfNativeError = 6844183, *pcbErrorMsg = 155, *ColumnNumber = -1, *RowNumber = 1
MessageText = "[DataDirect][ODBC PostgreSQL Wire Protocol driver][PostgreSQL]ERROR: relation "pk_item_id33" already exists(File index.c; Line 768; Routine index_create; )"
stmt:    szSqlState = "01000", *pfNativeError = -1, *pcbErrorMsg = 213, *ColumnNumber = -1, *RowNumber = 1
MessageText = "[DataDirect][ODBC PostgreSQL Wire Protocol driver][PostgreSQL]NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "pk_item_id33" for table "JFL_LEAK333"(File indexcmds.c; Line 578; Routine DefineIndex; )"
