Fixup some appendStringInfo and appendPQExpBuffer calls
A number of places were using appendStringInfo() when they could have beenusing appendStringInfoString() instead. While there's no functionalitychange there, it's just more efficient to use appendStringInfoString()when no formatting is required. Likewise for someappendStringInfoString() calls which were just appending a single char.We can just use appendStringInfoChar() for that.Additionally, many places were using appendPQExpBuffer() when they couldhave used appendPQExpBufferStr(). Change those too.Patch by Zhijie Hou, but further searching by me found significantly moreplaces that deserved the same treatment.Author: Zhijie Hou, David RowleyDiscussion:https://postgr.es/m/cb172cf4361e4c7ba7167429070979d4@G08CNEXMBPEKD05.g08.fujitsu.local
