Tom Lane f0d6f20278 Keep pg_stat_statements' query texts in a file, not in shared memory. ... This change allows us to eliminate the previous limit on stored query length, and it makes the shared-memory hash table very much smaller, allowing more statements to be tracked. (The default value of pg_stat_statements.max is therefore increased from 1000 to 5000.) In typical scenarios, the hash table can be large enough to hold all the statements commonly issued by an application, so that there is little "churn" in the set of tracked statements, and thus little need to do I/O to the file. To further reduce the need for I/O to the query-texts file, add a way to retrieve all the columns of the pg_stat_statements view except for the query text column. This is probably not of much interest for human use but it could be exploited by programs, which will prefer using the queryid anyway. Ordinarily, we'd need to bump the extension version number for the latter change. But since we already advanced pg_stat_statements' version number from 1.1 to 1.2 in the 9.4 development cycle, it seems all right to just redefine what 1.2 means.
