Various places that were using StringInfo but didn't need that StringInfo to exist beyond the scope of the function were using makeStringInfo(), which allocates both a StringInfoData and the buffer it uses as two separate allocations. It's more efficient for these cases to use a StringInfoData on the stack and initialize it with initStringInfo(), which only allocates the string buffer. This also simplifies the cleanup, in a few cases.
