Some review:
1) +1 to "REINDEX ALL IN SCHEMA name"
2) IMHO the logic should be exactly the same as REINDEX DATABASE, including
the transaction control. Imagine a schema with a lot of tables, you can
lead to a deadlock using just one transaction block.
3) The patch was applied to master and compile without warnings
4) Typo (... does not have any table)
+ if (!reindex_schema(heapOid))
+ ereport(NOTICE,
+ (errmsg("schema\"%s\" does not hava any table",
+ schema->relname)));
5) Missing of regression tests, please add it to
src/test/regress/sql/create_index.sql
6) You need to add psql complete tabs
7) I think we can add "-S / --schema" option do reindexdb in this patch
too. What do you think?
