![]() ![]() Options to be passed directly to the old postgres command multiple option invocations are appended -O options ![]() Generally, this option is useful for testing but should not be used on a production installation. This option causes pg_upgrade to return without waiting, which is faster, but means that a subsequent operating system crash can leave the data directory corrupt. Use hard links instead of copying files to the new cluster -Nīy default, pg_upgrade will wait for all files of the upgraded cluster to be written safely to disk. Number of simultaneous processes or threads to use -k The new database cluster configuration directory environment variable PGDATANEW -j njobs The old database cluster configuration directory environment variable PGDATAOLD -D configdir The new PostgreSQL executable directory default is the directory where pg_upgrade resides environment variable PGBINNEW -cĬheck clusters only, don't change any data -d configdir The old PostgreSQL executable directory environment variable PGBINOLD -B bindir Pg_upgrade supports upgrades from 9.2.X and later to the current major release of PostgreSQL, including snapshot and beta releases. ![]() It is important that any external modules are also binary compatible, though this cannot be checked by pg_upgrade. Pg_upgrade does its best to make sure the old and new clusters are binary-compatible, e.g., by checking for compatible compile-time settings, including 32/64-bit binaries. (The community will attempt to avoid such situations.) If a future major release ever changes the data storage format in a way that makes the old data format unreadable, pg_upgrade will not be usable for such upgrades. pg_upgrade uses this fact to perform rapid upgrades by creating new system tables and simply reusing the old user data files. Major PostgreSQL releases regularly add new features that often change the layout of the system tables, but the internal data storage format rarely changes. It is not required for minor version upgrades, e.g., from 9.6.2 to 9.6.3 or from 10.1 to 10.2. I have no experience with command prompts.Pg_upgrade (formerly called pg_migrator) allows data stored in PostgreSQL data files to be upgraded to a later PostgreSQL major version without the data dump/restore typically required for major version upgrades, e.g., from 9.5.8 to 9.6.4 or from 10.7 to 11.2. Then I opened the command prompt and typed "runas /user:postgres cmd.exe" Then this Window appeared:Īnd now I don't have a clue, what to type in there in order to run the postgreSQL installer. A new window appears, you need to run the.Create a new Windows user named postgres and add it to the Administrators groupĪs the postgres command using the following command: runas.Uninstall the PostgreSQL and delete the data directory in the installation folder.So I googled my problem and I found a tutorial here which should solve my problem. I have the widespread problem, that the prompt "Failed to load sql modules into the database cluster" shows up, when I try to install PostgreSQL. I tried to download PostgreSQL Version 9.6.1 for Windows x86-64 from. I have problems with installing PostgreSQL. ![]()
