Hi Tomas!

Reviewing the sgml documentation, I think something like the following should be added:

diff --git a/doc/src/sgml/catalogs.sgml b/doc/src/sgml/catalogs.sgml
index a0e6d7062b..108c4ec430 100644
--- a/doc/src/sgml/catalogs.sgml
+++ b/doc/src/sgml/catalogs.sgml
@@ -6496,7 +6496,9 @@ SCRAM-SHA-256$<replaceable>&lt;iteration count&gt;</replaceable>:<replaceable>&l
An array containing codes for the enabled statistic kinds;
valid values are:
