Introduce sequence_*() access functions Similarly to tables and indexes, these functions are able to open relations with a sequence relkind, which is useful to make a distinction with the other relation kinds. Previously, commands/sequence.c used a mix of table_{close,open}() and relation_{close,open}() routines when manipulating sequence relations, so this clarifies the code.
A direct effect of this change is to align the error messages produced when attempting DDLs for sequences on relations with an unexpected relkind, like a table or an index with ALTER SEQUENCE, providing an extra error detail about the relkind of the relation used in the DDL query.
