The following documentation comment has been logged on the website:

Description:
The default limit of 5000 statements applied by the pg_stat_statements.max
parameter is not mentioned until farther down in the article at F.32.4 . For
ease of reading and use by those of us that don't do configuration only
support, I recommend making a note either in F.32.1 or the main description
of F.32 to something of the degree:
"""
Note
This table/view is not an exhaustive list of all distinct queries. Only the
most commonly executed queries are saved up to a certain limit after which
the less executed queries are discarded. That limit is defined by
pg_stat_statements.max as described in section F.32.4 Configuration
Parameters.
