+ *
+ *
+ * Sequence access method allows the SQLStandard Sequence objects to be
+ * managed according to either the default access method or a pluggable
+ * replacement. Each object refers to one access method, though there can
+ * be many different access methods in use if required.
+ *
+ * SQLStandard assumes that each Sequence object is completely controlled
+ * from the current database node, preventing any form of clustering
+ * mechanisms from controlling behaviour. Sequence access methods are
+ * general purpose though designed specifically to address the needs of
+ * Sequences working as part of a multi-node "cluster", though that is
+ * not defined here, nor are there dependencies on anything outside of
+ * this module, nor any particular form of clustering.
+ *
+ * The SQL Standard behaviour, also the historical PostgreSQL behaviour,
+ * is referred to as the "Local" SeqAm. That is also the basic default.
+ * Local SeqAm assumes that allocations from the sequence will be
+ * contiguous, so if user1 requests a range of values and is given
+ * 500-599 as values for their backend then the next user to make a
+ * request will be given a range starting with 600.
+ *
+ * The SeqAm mechanism allows us to override the Local behaviour, for
+ * use with clustering systems. When multiple masters can request
+ * ranges of values it would break the assumption of contiguous
+ * allocation. It seems likely that the SeqAm would also wish to control
+ * node-level caches for sequences to ensure good performance.
+ * The CACHE option is not affected by this, since that works per backend.
+ *
+ * SeqAm allows calls to allocate a new range of values, reset the
+ * sequence to a new value and to define options for the AM module.
+ * The on-disk format of Sequences is the same for all AMs.
+ *
+ * We currently assume that there is no persistent state held
+ * within the SeqAm, so it is safe to ALTER the access method of an
+ * object without taking any special actions, as long as we hold an
+ * AccessExclusiveLock while we do that.
+ *
+ * SeqAMs work similarly to IndexAMs in many ways. pg_class.relam stores
+ * the Oid of the SeqAM, just as we do for IndexAm. The relcache stores
+ * AM information in much the same way for indexes and sequences, and
+ * management of options is similar also.
+ *
+ * Note that the SeqAM API calls are synchronous. It is up to the SeqAM
+ * to decide how that is handled, for example, whether there is a higher
+ * level cache at instance level to amortise network traffic in cluster.
+ *
+ * The SeqAM is identified by Oid of corresponding tuple in pg_seqam.
+ * There is no syscache for pg_seqam, though the SeqAm data is stored
+ * on the relcache entry for the sequence.
