pg_checkpointer is not a verb or verb phrase

Hi,

I was just looking at the list of predefined roles that we have, and
pg_checkpointer is conspicuously not like the others:

rhaas=# select rolname from pg_authid where oid!=10;
          rolname
---------------------------
 pg_database_owner
 pg_read_all_data
 pg_write_all_data
 pg_monitor
 pg_read_all_settings
 pg_read_all_stats
 pg_stat_scan_tables
 pg_read_server_files
 pg_write_server_files
 pg_execute_server_program
 pg_signal_backend
 pg_checkpointer
(12 rows)

Almost all of these are verbs or verb phrases: having this role gives
you the ability to read all data, or write all data, or read all
settings, or whatever. But you can't say that having this role gives
you the ability to checkpointer. It gives you the ability to
checkpoint, or to perform a checkpoint.

So I think the name is inconsistent with our usual convention, and we
ought to fix it.
