From 5734eb2c92a5efd665186c52b8eebdf2880868b5 Mon Sep 17 00:00:00 2001 From: Andrew Dunstan Date: Tue, 25 Jun 2013 13:45:03 -0400 Subject: [PATCH] Properly dump dropped foreign table cols in binary-upgrade mode. In binary upgrade mode, we need to recreate and then drop dropped columns so that all the columns get the right attribute number. This is true for foreign tables as well as for native tables. For foreign tables we have been getting the first part right but not the second, leading to bogus columns in the upgraded database. Fix this all the way back to 9.1, where foreign tables were introduced. --- src/bin/pg_dump/pg_dump.c | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) diff --git a/src/bin/pg_dump/pg_dump.c b/src/bin/pg_dump/pg_dump.c index 7b25e81020..72f172bf1f 100644 --- a/src/bin/pg_dump/pg_dump.c +++ b/src/bin/pg_dump/pg_dump.c @@ -12595,7 +12595,8 @@ dumpTableSchema(Archive *fout, TableInfo *tbinfo) * attislocal correctly, plus fix up any inherited CHECK constraints. * Analogously, we set up typed tables using ALTER TABLE / OF here. */ - if (binary_upgrade && tbinfo->relkind == RELKIND_RELATION) + if (binary_upgrade && (tbinfo->relkind == RELKIND_RELATION || + tbinfo->relkind == RELKIND_FOREIGN_TABLE) ) { for (j = 0; j < tbinfo->numatts; j++) { @@ -12613,8 +12614,13 @@ dumpTableSchema(Archive *fout, TableInfo *tbinfo) appendStringLiteralAH(q, fmtId(tbinfo->dobj.name), fout); appendPQExpBuffer(q, "::pg_catalog.regclass;\n"); - appendPQExpBuffer(q, "ALTER TABLE ONLY %s ", - fmtId(tbinfo->dobj.name)); + if (tbinfo->relkind == RELKIND_RELATION) + appendPQExpBuffer(q, "ALTER TABLE ONLY %s ", + fmtId(tbinfo->dobj.name)); + else + appendPQExpBuffer(q, "ALTER FOREIGN TABLE %s ", + fmtId(tbinfo->dobj.name)); + appendPQExpBuffer(q, "DROP COLUMN %s;\n", fmtId(tbinfo->attnames[j])); } -- 2.40.0
