The following bug has been logged online:
Bug reference: 3413
Logged by: Toru SHIMOGAKI
Email address: shimogaki.toru@oss.ntt.co.jp
PostgreSQL version: 8.2.4
Operating system: Red Hat Enterprise Linux AS4
Description: character string or multibyte character to "char"
Details:
When a character string or a multibyte character is inserted to "char"
column, no error occurs. Is this a bug? Should it be checked as "not single
character" in charin(), charrecv() and charout()?
Anyway, I can't find any spec descriptions in the following document;
http://www.postgresql.org/docs/8.2/static/datatype-character.html
