Consistency would trump getting a single entry right, for sure. I wonder, though, whether we shouldn't consistently distinguish them. For one thing, I've seen multiple posts where people were reporting "bugs" because of having confused char with "char". FWIW, \d shows: Table "pg_catalog.pg_class" Column | Type | Modifiers -----------------+-----------+----------- relname | name | not null relnamespace | oid | not null reltype | oid | not null reloftype | oid | not null relowner | oid | not null relam | oid | not null relfilenode | oid | not null reltablespace | oid | not null relpages | integer | not null reltuples | real | not null reltoastrelid | oid | not null reltoastidxid | oid | not null relhasindex | boolean | not null relisshared | boolean | not null relpersistence | "char" | not null relkind | "char" | not null relnatts | smallint | not null relchecks | smallint | not null relhasoids | boolean | not null relhaspkey | boolean | not null relhasexclusion | boolean | not null relhasrules | boolean | not null relhastriggers | boolean | not null relhassubclass | boolean | not null relfrozenxid | xid | not null relacl | aclitem[] | reloptions | text[] | Indexes: "pg_class_oid_index" UNIQUE, btree (oid) "pg_class_relname_nsp_index" UNIQUE, btree (relname, relnamespace) Currently we don't seem to distinguish them in very many places in the docs: $ find -name '*.sgml' | xargs egrep -n '\"char\"' ./doc/src/sgml/textsearch.sgml:1271:setweight(<replaceable class="PARAMETER">vector</replaceable> <type>tsvector</>, <replaceable class="PARAMETER">weight</replaceable> <type>"char"</>) returns <type>tsvector</> ./doc/src/sgml/datatype.sgml:1116: length might change in a future release.
