void end_query_trace(StatementInfo_ *stmt) if (stmt->perf_metrics) stmt->perf_metrics->query_end_time = get_current_time_ms(); uint64_t duration = stmt->perf_metrics->query_end_time - stmt->perf_metrics->query_start_time;

statement_cache = entry; return 0;

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: postgresql-odbc

Build Environment # Clone the repository git clone https://github.com/postgres/postgresql-odbc.git cd postgresql-odbc Configure with debug options ./configure --enable-debug --enable-unicode CFLAGS="-g -O0" Build make clean make make install Testing Your Feature // Add test in test/test_feature.c void test_new_connection_parameter() SQLHDBC hdbc; SQLRETURN ret; // Test connection with new parameter ret = SQLConnect(hdbc, (SQLCHAR*)"DSN=PostgreSQL;MyNewFeature=1", SQL_NTS, NULL, 0, NULL, 0); Adding a New Connection Parameter Here's how to

entry->statement_name = strdup(name); entry->sql = strdup(sql); entry->last_used = time(NULL); entry->use_count = 1; entry->next = statement_cache; statement_name = strdup(name)

// In prepared.c typedef struct StatementCacheEntry char *statement_name; char *sql; PGresult *prepared_result; time_t last_used; int use_count; struct StatementCacheEntry *next; StatementCacheEntry; static StatementCacheEntry *statement_cache = NULL;
