<< unrecognized configuration parameter "pg_stat_statements.track" >>

Works correctly in 9.2.10 but not in 9.1.8. Is this a known bug for 9.1.8
that has an upstream fix? There is nothing in the 9.1.x release notes
indicating such.

shared_preload_libraries='pg_stat_statements'
track_activity_query_size=2048
pg_stat_statements.track = all

The above configuration in 9.1.8 fails with "unrecognized configuration
parameter "pg_stat_statements.track""
When the "track" option is removed, startup is normal. When added back and
reload issued, again the complaint.

The shared library does indeed have the option string:

# strings /usr/lib64/pgsql/pg_stat_statements.so |grep track
pgstat_track_activity_query_size
pg_stat_statements.track
Sets the maximum number of statements tracked by pg_stat_statements.
Selects which statements are tracked by pg_stat_statements.
Selects whether utility commands are tracked by pg_stat_statements.
pg_stat_statements.track_utility
