postgresql 9.3 - Insert hex value in escape format (bytea) -

how insert hex value \x320000000d2f2100 in escape format bytea field ?

bytea_output settings set escape

the bytea_output setting has nil how bytea interpreted server, how it's sent client.

do want insert literal string \x320000000d2f2100 (as 7-bit ascii), i.e. producing bytes 0x5c 0x78 0x33 0x32 0x30 0x30 0x30 0x30 0x30 0x30 0x30 0x64 0x32 0x66 0x32 0x31 0x30 0x30?

if so, escape backslash, documented in syntax escape format bytea literals.

regress=> select bytea '\\x320000000d2f2100'; bytea ---------------------------------------- \x5c7833323030303030303064326632313030 (1 row)

do want insert bytes 0x32 0x00 0x00 0x00 0x0d 0x2f 0x21 0x00, i.e. hex value? if so, don't escape backslash. doesn't matter setting of bytea_output is.

regress=> select bytea '\x320000000d2f2100'; bytea -------------------- \x320000000d2f2100 (1 row)
