You might need to add explicit type casts./ I am not able to figure it out what is wrong here. Can Any body point out what is wrong here. Thanks is advance. -- View this message in context: http://postgresql.1045698.n5.nabble.com/Conversion-from-CHAR-HEX-tp5805115.html Sent from the PostgreSQL - general mailing list archive at Nabble.com.
