Fixup various StringInfo function usages
This adjusts various appendStringInfo* function calls to use a moreappropriate and efficient function with the same behavior. For example,use appendStringInfoChar() when appending a single character rather thanappendStringInfo() and appendStringInfoString() when no formatting isrequired rather than using appendStringInfo().All adjustments made here are in code that's new to v17, so it makessense to fix these now rather than wait a few years and makebackpatching harder.Discussion:https://postgr.es/m/CAApHDvojY2UvMiO+9_55ArTj10P1LBNJyyoGB+C65BLDNT0GsQ@mail.gmail.comReviewed-by: Nathan Bossart, Tom Lane
