With psql: \lo_import /path/to/file It creates a large object with the contents of the file from the client file system and returns its unique ID, in the output and into the :LASTOID variable in psql. There's no equivalent for bytea contents. Bytea contents need to be either injected into the query as text, or passed separately as parameters, but psql does not provide helper methods for this, and it also lack binary support for variables. So it's easier to implement "upload bytea to server" in a script language than in psql. Alternatively, if you don't care about the contents being written twice, a file can be imported as a large object, copied as bytea into a row of the target table, and the large object purged immediately. In psql, a sequence like this should work: \lo_import /path/to/file \set tmp_oid :LASTOID insert into tablename ( bytea_col, [other columns] ) values ( lo_get(:tmp_oid), [other values] ) \lo_unlink :tmp_oid Best regards, -- Daniel Vérité PostgreSQL-powered mailer: http://www.manitou-mail.org Twitter: @DanielVerite
