pg_stat_statements: Expand tests for SET statements There are many grammar flavors that depend on the parse node VariableSetStmt. This closes the gap in pg_stat_statements by providing test coverage for what should be a large majority of them, improving more the work begun in de2aca288569. This will be used to ease the evaluation of a path towards more normalization of SET queries with query jumbling.
Note that SET NAMES (grammar from the standard, synonym of SET client_encoding) is omitted on purpose, this could use UTF8 with a conditional script where UTF8 is supported, but that does not seem worth the maintenance cost for the sake of these tests. The author has submitted most of these in a TAP test (filled in any holes I could spot), still queries in a SQL file of pg_stat_statements is able to achieve the same goal while being easier to look at when testing normalization patterns.
