Hi List(s); I'm wanting to find more details per the following methods, can someone explain to me exactly what each of these methods is, how its implemented in postgres or point me to some docs or README's that explain these methods? Some of 'em are obviously no-brainers but I'm writing a postgres book and want to make sure I convey the concepts properly and technically correct. - Bitmap Scans - Hash Aggregation - Hash Joins - Index Scans - Merge Joins - Nested Loop Joins - TID Scans Thanks in advance for your help...
