| Parameter | Effect | When to Enable | |-----------|--------|----------------| | UseServerSidePrepare | Forces PREPARE for all parameterized queries. | High-frequency same-shaped queries. | | UseDeclareFetch | Emulates scrollable cursors via DECLARE ... CURSOR + FETCH | Large result sets, backward scrolling needed. | | Fetch=100 (or N) | Rows fetched per network round-trip. | Tune between 10–1000 for wide tables. | | DisableOptimizer | Forces generic plans in prepared statements. | Avoids row-count-specific bad plans. | | ByteaAsLongVarBinary | Maps bytea to SQL_LONGVARBINARY . | Required for large binary data in some BI tools. |

: Using UseDeclareFetch=1 forces every SELECT to become a server-side cursor, which can cause massive temp file usage if the result set is large and you scroll backward. odbc postgresql driver
