Make use of the statement boundary info added by commit ab1f0c822 to let pg_stat_statements behave more sanely when multiple SQL queries are jammed into one query string. It now records just the relevant part of the source string, not the whole thing, for each individual query. Even when no multi-statement strings are involved, users may notice small changes in the output: leading and trailing whitespace and semicolons will be stripped from statements, which did not happen before. Also, significantly expand pg_stat_statements' regression test script.
