Hi Laurenz, Thanks for your reply. Sorry for the double posting here and StackOverflow http://stackoverflow.com/questions/39518417/unable-to-create-oracle-fdw-extension-on-postgres . I will update the details on StackOverflow since formatting and editing are easier there.

Re: [GENERAL] Unable to create oracle_fdw (foreign data wrapper) extension
Thanks again, Scott. No success yet though. I uninstalled Oracle instant client 12.1 using dpkg, downloaded RPMs for instant client 10.2 and installed them with alien. I also downloaded oracle_fdw 1.4 and installed it, since I was getting this error with oracle_fdw 1.5: --- postgres=# create extension oracle_fdw; ERROR: could not load library "/usr/lib/postgresql/9.4/lib/oracle_fdw.so": libclntsh.so.12.1: cannot open shared object file: No such file or directory --- Once I installed oracle_fdw 1.4 I got this: # ldd /usr/lib/postgresql/9.4/lib/oracle_fdw.so linux-vdso.so.1 => (0x7ffc3b5ec000) libclntsh.so.10.1 => /usr/lib/oracle/10.2.0.3/client64/lib/libclntsh.so.10.1 (0x7f7251471000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x7f72510e6000) libnnz10.so => /usr/lib/oracle/10.2.0.3/client64/lib/libnnz10.so (0x7f7250c42000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x7f7250a3e000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x7f72507bc000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x7f725059f000) libnsl.so.1 => /lib/x86_64-linux-gnu/libnsl.so.1 (0x7f7250387000) /lib64/ld-linux-x86-64.so.2 (0x7f7252a3b000) But again when I try to load the extension I get the same error and Postgres crashes. When I look in the latest log file at /var/lib/postgresql/9.4/main/pg_log I see these lines: --- t=2016-09-15 16:16:08 PDT d= h= p=25327 a=LOG: 0: server process (PID 20397) was terminated by signal 11: Segmentation fault t=2016-09-15 16:16:08 PDT d= h= p=25327 a=DETAIL: Failed process was running: create extension oracle_fdw; t=2016-09-15 16:16:08 PDT d= h= p=25327 a=LOCATION: LogChildExit, postmaster.c:3347 t=2016-09-15 16:16:08 PDT d= h= p=25327 a=LOG: 0: terminating any other active server processes t=2016-09-15 16:16:08 PDT d= h= p=25327 a=LOCATION: HandleChildCrash, postmaster.c:3068 t=2016-09-15 16:16:08 PDT d=svp2 h=127.0.0.1 p=19672 a=[unknown] WARNING: 57P02: terminating connection because of crash of another server process t=2016-09-15 16:16:08 PDT d=svp2 h=127.0.0.1 p=19672 a=[unknown] DETAIL: The postmaster has commanded this server process to roll back the current transaction and exit, because another server process exited abnormally and possibly corrupted shared memory. t=2016-09-15 16:16:08 PDT d=svp2 h=127.0.0.1 p=19672 a=[unknown] HINT: In a moment you should be able to reconnect to the database and repeat your command. t=2016-09-15 16:16:08 PDT d=svp2 h=127.0.0.1 p=19672 a=[unknown] LOCATION: quickdie, postgres.c:2581 t=2016-09-15 16:16:08 PDT d= h= p=19668 a=WARNING: 57P02: terminating connection because of crash of another server process --- On Thu, Sep 15, 2016 at 2:58 PM, Scott Mead wrote: > > > On Thu, Sep 15, 2016 at 4:57 PM, Arun Rangarajan > wrote: > >> Thanks, Scott. >> >> oracle_fdw version 1.5.0 from http://pgxn.org/dist/oracle_fdw/ >> >> Oracle client version: instantclient 12.1 >> > > I've had problems using anything > instant client 10.

[GENERAL] Unable to create oracle_fdw (foreign data wrapper) extension
I am following the instructions here: http://blog.dbi-services.com/connecting-your-postgresql-instance-to-an-oracle-database/ to install Oracle foreign data wrapper, oracle_fdw, on a PostgreSQL server. --- Oracle version: Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production, running on Red Hat Linux 7.2 PostgreSQL version: PostgreSQL 9.4.4 on x86_64-unknown-linux-gnu, compiled by gcc (Debian 4.7.2-5) 4.7.2, 64-bit, running on Debian 7 (wheezy). --- I was able to install sqlplus and connect from PostgreSQL server to Oracle server using sqlplus successfully, so connectivity is not a problem. But when I try to create the extension, I get the following error: --- postgres=# create extension oracle_fdw; server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. The connection to the server was lost. Attempting reset: Failed. --- Then I took clues from https://github.com/dalibo/pg_qualstats/issues/1 and added oracle_fdw to shared_preload_libraries in postgresql.conf like this: shared_preload_libraries = 'oracle_fdw' but now I can't restart Postgres: --- # service postgresql restart [] Restarting PostgreSQL 9.4 database server: main[] The PostgreSQL server failed to start. Please check the log output: t=2016-09-15 11:05:42 PDT d= h= p=23300 a=FATAL: XX000: invalid cache ID[FAILt=2016-09-15 11:05:42 PDT d= h= p=23300 a=LOCATION: SearchSysCacheList, syscache.c:1219 ... failed! failed! --- Looking into /var/log/postgresql/postgresql-9.4-main.log I only see these two lines: t=2016-09-15 11:05:42 PDT d= h= p=23300 a=FATAL: XX000: invalid cache ID: 41 t=2016-09-15 11:05:42 PDT d= h= p=23300 a=LOCATION: SearchSysCacheList, syscache.c:1219 Removing oracle_fdw from shared_preload_libraries allows postgres to be restarted, so this is the one causing restart to fail. How to fix this and get the foreign data wrapper working? Thank you.
