Tom Lane ad950ea98e Fix possible crash in pg_dump with identity sequences. If an owned sequence is considered interesting, force its owning table to be marked interesting too. This ensures, in particular, that we'll fetch the owning table's column names so we have the data needed for ALTER TABLE ... ADD GENERATED. Previously there were edge cases where pg_dump could get SIGSEGV due to not having filled in the column names. (The known case is where the owning table has been made part of an extension while its identity sequence is not a member; but there may be others.) Also, if it's an identity sequence, force its dumped-components mask to exactly match the owning table: dump definition only if we're dumping the table's definition, dump data only if we're dumping the table's data, etc. This generalizes the code introduced in commit `b965f2617` that set the sequence's dump mask to NONE if the owning table's mask is NONE. That's insufficient to prevent failures, because for example the table's mask might only request dumping ACLs, which would lead us to still emit ALTER TABLE ADD GENERATED even though we didn't create the table. It seems better to treat an identity sequence as though it were an inseparable aspect of the table, matching the treatment used in the backend's dependency logic. Perhaps this policy needs additional refinement, but let's wait to see some field use-cases before changing it further. While here, add a comment in pg_dump.h warning against writing tests like "if (dobj->dump == DUMP_COMPONENT_NONE)", which was a bug in this case. There is one other example in getPublicationNamespaces, which if it's not a bug is at least remarkably unclear and under-documented. Changing that requires a separate discussion, however. Per report from Artur Zakirov. Back-patch to all supported branches. Discussion: https://postgr.es/m/CAKNkYnwXFBf136=u9UqUxFUVagevLQJ=zGd5BsLhCsatDvQsKQ@mail.gmail.com		1 year ago

PostgreSQL Database Management System

This directory contains the source code distribution of the PostgreSQL database management system.

PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings.

General documentation about this version of PostgreSQL can be found at https://www.postgresql.org/docs/17/. In particular, information about building PostgreSQL from the source code can be found at https://www.postgresql.org/docs/17/installation.html.

The latest version of this software, and related software, may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
