I'll help you develop a feature for the PostgreSQL ODBC driver ( psqlodbc ). Since you haven't specified the exact feature, I'll provide a comprehensive guide for implementing a common feature, and you can let me know if you need something specific. 1. Adding a New Connection Parameter Here's how to add a new ODBC connection parameter:

// In connection.h typedef struct // ... existing fields char my_new_param[256]; // new parameter int my_new_feature_enabled; ConnectionInfo_; // In connection.c - parse connection string static int parse_connection_string(ConnectionInfo_ *ci, const char *conn_str) // ... existing parsing code

int cache_prepared_statement(ConnectionInfo_ *ci, const char *name, const char *sql) StatementCacheEntry *entry = malloc(sizeof(StatementCacheEntry)); if (!entry) return -1;
