From af34451db26a11543196f52464849774e5a3fe59 Mon Sep 17 00:00:00 2001 From: Mahendra Singh Thalor Date: Mon, 3 Feb 2025 01:27:29 +0530 Subject: [PATCH] pg_dumpall with directory|tar|custom format and restore it by pg_restore new option to pg_dumpall: -F, --format=d|t|c|p output file format ( plain text (default)) Ex:1 ./pg_dumpall --format=directory --file=dumpDirName Ex:2 ./pg_dumpall --format=tar --file=dumpDirName Ex:3 ./pg_dumpall --format=custom --file=dumpDirName Ex:4 ./pg_dumpall --format=plain --file=dumpDirName dumps are as: global.dat ::: global sql commands in simple plain format map.dat. ::: dboid dbname ---entries for all databases in simple text form databases. ::: subdir dboid1 -> toc.dat and data files in archive format subdir dboid2. -> toc.dat and data files in archive format etc --------------------------------------------------------------------------- NOTE: if needed, restore single db by particular subdir Ex: ./pg_restore --format=directory -d postgres dumpDirName/databases/5 -- here, 5 is the dboid of postgres db -- to get dboid, refer dbname in map.file -------------------------------------------------------------------------- new options to pg_restore: -g, --globals-only restore only global objects, no databases --exclude-database=PATTERN exclude database whose name matches pattern When we give -g/--globals-only option, then only restore globals, no db restoring. Design: When --format=d|t|c is specified and there is no toc.dat in main directory, then check for global.dat to restore all databases. If global.dat file is exist in directory, then first restore all globals from global.dat and then restore all databases one by one from map.dat list (if exist) TODO1: We need to think for --exclude-database=PATTERN for pg_restore. as of now, SELECT 1 WHERE XXX OPERATOR(pg_catalog.~) '^(PATTERN)$' COLLATE pg_catalog.default if db connection, if no db connection, then PATTERN=NAME matching only TODO2: We need to make changes for exit_nicely as we are one entry for each database while restoring. MAX_ON_EXIT_NICELY TODO3: some more test cases for new added options. TODO4: We can dump and restore databases in parallel mode. This needs more study thread: https://www.postgresql.org/message-id/flat/CAKYtNAp9vOtydXL3_pnGJ%2BTetZtN%3DFYSnZSMCqXceU3mkHPxPg%40mail.gmail.com#066433cb5ae007cbe35fefddf796d52f --- doc/src/sgml/ref/pg_dumpall.sgml | 80 ++- doc/src/sgml/ref/pg_restore.sgml | 31 + src/bin/pg_dump/Makefile | 8 +- src/bin/pg_dump/common_dumpall_restore.c | 286 +++++++++ src/bin/pg_dump/common_dumpall_restore.h | 26 + src/bin/pg_dump/meson.build | 2 + src/bin/pg_dump/pg_backup.h | 4 +- src/bin/pg_dump/pg_backup_archiver.c | 22 +- src/bin/pg_dump/pg_backup_tar.c | 2 +- src/bin/pg_dump/pg_backup_utils.c | 3 +- src/bin/pg_dump/pg_dump.c | 2 +- src/bin/pg_dump/pg_dumpall.c | 552 ++++++++-------- src/bin/pg_dump/pg_restore.c | 773 ++++++++++++++++++++++- src/bin/pg_dump/t/001_basic.pl | 9 + src/tools/pgindent/typedefs.list | 2 + 15 files changed, 1476 insertions(+), 326 deletions(-) create mode 100644 src/bin/pg_dump/common_dumpall_restore.c create mode 100644 src/bin/pg_dump/common_dumpall_restore.h mode change 100644 => 100755 src/bin/pg_dump/t/001_basic.pl diff --git a/doc/src/sgml/ref/pg_dumpall.sgml b/doc/src/sgml/ref/pg_dumpall.sgml index 39d93c2c0e3..6e1975f5ff0 100644 --- a/doc/src/sgml/ref/pg_dumpall.sgml +++ b/doc/src/sgml/ref/pg_dumpall.sgml @@ -16,7 +16,7 @@ PostgreSQL documentation pg_dumpall - extract a PostgreSQL database cluster into a script file + extract a PostgreSQL database cluster based on specified dump format @@ -121,7 +121,83 @@ PostgreSQL documentation Send output to the specified file.
