| 114 | When you SELECT bytea type, PostgreSQL returns octal byte value

|

| 120 | 7.2.0 and 7.2.1, bytea type must be casted when you enable
|
|---|
| 121 | multi-byte support. i.e. <TT
|
|---|
| 122 | CLASS="literal"
|

| 123 | >INSERT INTO test_table (image)

|

|
|---|
| 127 | character encoding does not match, there may be multi-byte
|
|---|
| 128 | stream error. User must cast to bytea to avoid this error.
