I find Tom's analogy to datestyle and bytea_output convincing. +1 for a GUC that changes the behaviour of boolout. And also +1 for doing anything at all to improve on the t/f output. Those glyphs are way too similar to each other. I think U+2713 and U+2717 (✓ and ✗) are the obvious choices for a boolean, but if we have a GUC we can set this to taste. Cheers, BJ
