Hi there,
I have a Centos 7 box with unixODBC 2.3.1 and postgresql-odbc 12.02
installed, which is connecting to a PostgreSQL server also running
v12.
Although I believe I have configured ODBC to use the v12.0 protocol,
it does not seem to be. When connected to the server and attempting to
get a list of columns in a table I get the error, “column c.relhasoids
does not exist”. This column was removed from pg_catalog.pg_class in
PostgreSQL v12.
postgresql-odbc was specifically updated to not use this column when
the protocol is v12 so I can only assume I’m not:
https://git.postgresql.org/gitweb/?p=psqlodbc.git;a=blob;f=info.c;h=f19032147ee1794e9685e7bc88293df6769c49c9;hb=HEAD#l2352
I have Protocol = 12.0 in my /etc/odbcinst.ini and if I run `strace
isql my-connector` I can see it loading the postgresql12 libs from
/usr/pgsql-12 as configured.
I’m stumped!
# isql my-connector -v -3
