pg_restore: connecting to database for restore
pg_restore: executing SELECT pg_catalog.set_config('search_path', '', false);
pg_restore: implied no-schema restore
pg_restore: database restoring skipped because option -g/--globals-only was specifiedwe should probably add some message there.
Please refer this scenario where "--no-comments" switch is ignoring when used with -Ft/c option of pg_dumpall
Test Case to reproduce:
--Connect to psql terminal , create a table and comment :
postgres=# create table t(n int);CREATE TABLE
postgres=# insert into t values (1);
INSERT 0 1
postgres=# comment on table t is 'testing...';
COMMENT
postgres=# SELECT obj_description('public.t'::regclass, 'pg_class') AS table_comment ;
table_comment
---------------
testing...
(1 row)
---------------
testing...
(1 row)
--perform pg_dumpall with
(a) -Fp (./pg_dumpall -Fp --no-comments -f dump.plain)
(b) -Ft (./pg_dumpall -Ft --no-comments -f dump.tar)
Case 1: restore (a) , just run the file (dump.plain) on psql terminal , fire this query :
postgres=# SELECT
obj_description('public.t'::regclass, 'pg_class') AS table_comment;
table_comment
---------------
(1 row)
obj_description('public.t'::regclass, 'pg_class') AS table_comment;
table_comment
---------------
(1 row)
Seems expected .
Case 2: restore (b) via command ( ./pg_restore -Ft dump.tar -d postgres -p 5806 -C )
fire this query :
postgres=# SELECT obj_description('public.t'::regclass, 'pg_class') AS table_comment ;
table_comment
---------------
testing...
(1 row)
---------------
testing...
(1 row)
Seems not expected i.e pg_dumpall with option -Ft still taking table comments and ignoring --no-comments switch.
