2025-03-26Use PG_MODULE_MAGIC_EXT in our installable shared libraries.Tom Lane
It seems potentially useful to label our shared libraries with version information, now that a facility exists for retrieving that. This patch labels them with the PG_VERSION string. There was some discussion about using semantic versioning conventions, but that doesn't seem terribly helpful for modules with no SQL-level presence; and for those that do have SQL objects, we typically expect them to support multiple revisions of the SQL definitions, so it'd still not be very helpful. I did not label any of src/test/modules/. It seems unnecessary since we don't install those, and besides there ought to be someplace that still provides test coverage for the original PG_MODULE_MAGIC macro.

2023-01-11Common function for percent placeholder replacementPeter Eisentraut
There are a number of places where a shell command is constructed with percent-placeholders (like %x). It's cumbersome to have to open-code this several times. This factors out this logic into a separate function. This also allows us to ensure consistency for and document some subtle behaviors, such as what to do with unrecognized placeholders. The unified handling is now that incorrect and unknown placeholders are an error, where previously in most cases they were skipped or ignored. This affects the following settings: - archive_cleanup_command - archive_command - recovery_end_command - restore_command - ssl_passphrase_command The following settings are part of this refactoring but already had stricter error handling and should be unchanged in their behavior: - basebackup_to_shell.command Reviewed-by: Nathan Bossart <nathandbossart@gmail.com> Discussion: https://www.postgresql.org/message-id/flat/5238bbed-0b01-83a6-d4b2-7eb0562a054e%40enterprisedb.com

2022-03-15Add 'basebackup_to_shell' contrib module.Robert Haas
As a demonstration of the sort of thing that can be done by adding a custom backup target, this defines a 'shell' target which executes a command defined by the system administrator. The command is executed once for each tar archive generate by the backup and once for the backup manifest, if any. Each time the command is executed, it receives the contents of th file for which it is executed via standard input. The configured command can use %f to refer to the name of the archive (e.g. base.tar, $TABLESPACE_OID.tar, backup_manifest) and %d to refer to the target detail (pg_basebackup --target shell:DETAIL). A target detail is required if %d appears in the configured command and forbidden if it does not. Patch by me, reviewed by Abhijit Menon-Sen.
