Arguments

+Portal +`+portal+`: portal containing the cursor
+bool +`+forward+`: true for fetch forward, false for fetch backward
+long +`+count+`: maximum number of rows to fetch

Return Value

SPI_processed and SPI_tuptable are set as in SPI_execute if successful.

Notes

Fetching backward may fail if the cursor’s plan was not created with the CURSOR_OPT_SCROLL option.
