Rahim Kanji	249b3d8725	* Replace C-style array with std::array in PgSQL_Connection ... * Nulling startup_parameters[i] in ~PgSQL_Connection after freeing	7 months ago
Rahim Kanji	50243ef283	Corrected RESET/DEFAULT logic ... * Now will actually reset value to server default (represented by nullptr value), if that parameter is not set in startup parameter. * Default parameter values (pgsql_default_*) will now be set only for critical parameters.	7 months ago
Rahim Kanji	1bcd09044b	Refactor Connection Reset Handling ... * Introduced startup parameters in PgSQL_Connection (removed default session parameters from PgSQL_Session) * Startup parameters are populated during both frontend and backend connection creation * Parameters provided via connection options are set as startup parameters * Backend connection parameter handling updated: only critical variables are now set via connection options to prevent interference with DISCARD ALL during connection reset; remaining parameters will be applied using individual SET commands	7 months ago

Rahim Kanji	03c08d2e1f	Introduced a new function in libpq, PShandleRowData, to handle incoming ... messages from the PostgreSQL backend. This function specifically checks for messages containing row data (indicated by 'D') and processes them efficiently. By providing direct access to the internal libpq buffer, it eliminates the need to allocate new memory for each row of data.	2 years ago
