Combine some duplicated code stanzas by creating small functions. Most of these duplications arose at a time when I wouldn't have trusted C compilers to auto-inline small functions intelligently, but they're probably poor practice now. Similarly split out some bits that aren't actually duplicative as the code stands, but would become so after an upcoming patch to add another error-handling code path. Take the opportunity to add some lengthier comments about what we're doing here, too. Re-order one function that seemed not very well-placed. Patch by me, per suggestions from Andres Freund.
