Tom Lane d951d6065d Avoid O(N^2) behavior when enlarging SPI tuple table in spi_printtup(). ... For no obvious reason, spi_printtup() was coded to enlarge the tuple pointer table by just 256 slots at a time, rather than doubling the size at each reallocation, as is our usual habit. For very large SPI results, this makes for O(N^2) time spent in repalloc(), which of course soon comes to dominate the runtime. Use the standard doubling approach instead. This is a longstanding performance bug, so back-patch to all active branches. Neil Conway		2015-08-21 20:32:33 -04:00
