Hi Tom,
Your example works fine in psql:regression=# create table t1 (f1 bytea); CREATE TABLE regression=# insert into t1 values (E'IsLoggedIn|b:1;CurrentUser|O:17:"Class_SystemUser":4:{s:26:"\\000Class_SystemUser}'::bytea); INSERT 0 1 regression=# select * from t1;f1 -----------------------------------------------------------------------------------IsLoggedIn|b:1;CurrentUser|O:17:"Class_SystemUser":4:{s:26:"\000Class_SystemUser} (1 row) I suspect what is happening is that some layer on the client side is doubling (or perhaps undoubling?) the backslashes for you. Exactly what are you doing with that literal as you build the query? It might help to turn on log_statements so that you can see just what the server is getting.
Many thanks for your reply. I was a bit naive about the quality of the client I was using (Navicat 8.1.) It turns out in the "Memo" view it doesn't show anything past the first zero byte. However switch it to hex view and you see the full bytes.
I think my issue that it wasn't working on the client side (and caused me to examine it in more detail in the database) was because it wasn't unescaping correctly in the application code when it read the data back out of the database.
Next time I won't be so lazy and try it out in psql first... Regards, Andy -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
