Added class Base_STMT_Global_info
Also adding new debug modules
process_mysql_query() extract queries at different offsets depending if: * MySQL (COM_QUERY, COM_STMT_PREPARE, COM_STMT_EXECUTE) * PostgreSQL (Simple query) * PostgreSQL (PARSE)
Not working, just placeholders
PgSQL_Connection.cpp now includes extra header to access PostgreSQL internals. To achieve that some postgres headers were modified, and ProxySQL code needs to define PG_SYM_PROXYSQL (see PgSQL_Connection.cpp as example).
Use of PQsendQueryPrepared() instead of PQsendQueryParams() . PQsendQueryParams() sends also a Parse packet , but we had the query already parsed . Fixed how resultFormat is evaluated. Hardcoded stmtName `proxysql_ps_1` : this is temporary
Nothing significant
