Hello, according to the Postgres website. https://yum.postgresql.org/news-packagelist.php oracle_fdw should be available from the Postgres yum repository. However, my CentOS 7 test server can't find that package: "yum repolist" confirms I have both the Postgres 10 and Postgres 11 repositories installed: [root@centos01 ~]# yum repolist Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: centos.schlundtech.de * epel: mirror.netweaver.uk * extras: centos.mirror.net-d-sign.de * updates: centos.mirror.iphh.net repo id repo name base/7/x86_64 CentOS-7 - Base epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 extras/7/x86_64 CentOS-7 - Extras pgdg10/7/x86_64 PostgreSQL 10 7 - x86_64 pgdg11/7/x86_64 PostgreSQL 11 7 - x86_64 pipelinedb_pipelinedb/x86_64 pipelinedb_pipelinedb pipelinedb_pipelinedb-source pipelinedb_pipelinedb-source updates/7/x86_64 CentOS-7 - Updates However, yum doesn't see an oracle_fdw package: [root@centos01 ~]# yum list available | grep fdw cstore_fdw_10.x86_64 1.6.2-1.rhel7 pgdg10 cstore_fdw_10-debuginfo.x86_64 1.6.2-1.rhel7 pgdg10 cstore_fdw_11.x86_64 1.6.2-1.rhel7.1 pgdg11 cstore_fdw_11-debuginfo.x86_64 1.6.2-1.rhel7.1 pgdg11 hdfs_fdw_10.x86_64 2.0.4-1.rhel7 pgdg10 hdfs_fdw_10-debuginfo.x86_64 2.0.4-1.rhel7 pgdg10 hdfs_fdw_11.x86_64 2.0.4-1.rhel7 pgdg11 hdfs_fdw_11-debuginfo.x86_64 2.0.4-1.rhel7 pgdg11 mailchimp_fdw.x86_64 0.3.1-2.rhel7.1 pgdg11 mongo_fdw10.x86_64 5.2.0-1.rhel7 pgdg10 mongo_fdw10-debuginfo.x86_64 5.2.0-1.rhel7 pgdg10 mysql_fdw_10.x86_64 2.5.0-1.rhel7 pgdg10 mysql_fdw_10-debuginfo.x86_64 2.5.0-1.rhel7 pgdg10 mysql_fdw_11.x86_64 2.5.0-1.rhel7 pgdg11 mysql_fdw_11-debuginfo.x86_64 2.5.0-1.rhel7 pgdg11 ogr_fdw10.x86_64 1.0.7-1.rhel7 pgdg10 ogr_fdw10-debuginfo.x86_64 1.0.7-1.rhel7 pgdg10 ogr_fdw11.x86_64 1.0.7-1.rhel7 pgdg11 ogr_fdw11-debuginfo.x86_64 1.0.7-1.rhel7 pgdg11 osm_fdw10.x86_64 3.0.0-1.f30 pgdg10 sqlite_fdw10.x86_64 1.0.0-1.rhel7 pgdg10 sqlite_fdw10-debuginfo.x86_64 1.0.0-1.rhel7 pgdg10 tds_fdw10.x86_64 1.0.8-1.rhel7 pgdg10 tds_fdw10-debuginfo.x86_64 1.0.8-1.rhel7 pgdg10 Is compiling oracle_fdw the only chance I have?
