Michael Paquier 6da67a0c11 doc: Mention de-normalization of deallocated entries in pg_stat_statements ... The current implementation of query normalization in pg_stat_statements is optimistic. If an entry is deallocated between the post-analyze hook and the planner and/or execution hook, it can be possible to find query strings with literal constant values (like "SELECT 1, 2") rather than their normalized flavor (like "SELECT $1, $2"). This commit adds in the documentation a paragraph about this limitation, and that this risk can be reduced by increasing pg_stat_statements.max, particularly if pg_stat_statements_info reports a high number of deallocations.
