Hi all, this should be trivial, but if I dump and restore the very same database the restored one is bigger than the original one. I did vacuumed the database foo, then dumped and restored into bar, and the latter, even when vacuumed, remains bigger then the original one. No other activity was running on the cluster. What am I missing here? % vacuumdb --full foo vacuumdb: vacuuming database "foo" % pg_dump -Fd -f backup_foo.d -U postgres foo % createdb bar % pg_restore -Fd backup_foo.d -U postgres -d bar % psql -U postgres -c '\x' -c "SELECT pg_database_size( 'foo' ), pg_database_size( 'bar' );" template1 Expanded display is on. -[ RECORD 1 ]----+----------- pg_database_size | 2686571167 pg_database_size | 2690212355 % vacuumdb --full bar vacuumdb: vacuuming database "bar" % psql -U postgres -c '\x' -c "SELECT pg_database_size( 'foo' ), pg_database_size( 'bar' );" template1 Expanded display is on. -[ RECORD 1 ]----+----------- pg_database_size | 2686571167 pg_database_size | 2688193183 % psql -c 'select version();' -U postgres template1 version ----------------------------------------------------------------------------------------------------------------------------------------------------- PostgreSQL 11.3 on amd64-portbld-freebsd12.0, compiled by FreeBSD clang version 6.0.1 (tags/RELEASE_601/final 335540) (based on LLVM 6.0.1), 64-bit (1 row)
