Currently, yum installation is only supported on the openEuler 22.03 LTS operating system, and both arm64 and x86_64 architectures are supported.
The database integrated into the openEuler system is built based on the capabilities of the openGauss lightweight version.
Only the stand-alone database instance is installed in the RPM mode. During the upgrade, only the binary version can be replaced, and grayscale upgrade is not supported.
The default installation instance listens to the 127.0.0.1:7654 address and port. If you need to connect remotely, you need to manually modify the listen_address in the postgresql.conf file.
