I remember running tests `testShowTables()` and other relevant test with
this patch on master branch and since they passed in QA, i think there should
not be any issue with this straight-forward backport.

> Currently users rely on {{!tables}} and {{!schemas}} commands provided by
> sqlline which pulls the information using the standard JDBC metadata calls
> like {{getTables()}} and {{getSchemas()}}.
> Most other databases (like mysql[1,2]) implement these as first class SQL
> commands that gives the user more flexibility in querying by adding necessary
> filters and looking up for table information in specific schemas. The ask
> here is to implement the following SQL commands.
> {noformat}
> SHOW SCHEMAS [LIKE '<pattern>']
> SHOW TABLES [IN <schema>] [LIKE '<pattern>']
> {noformat}
