Re: [PATCH] Add pg_get_table_ddl() to reconstruct CREATE TABLE statements

 Thanks for the continued review. I've rebased and updated the patch.

Andrew's commit replaced the VARIADIC text[] option interface on
pg_get_role_ddl(),
pg_get_tablespace_ddl(), and pg_get_database_ddl() with typed named boolean
parameters. pg_get_table_ddl() now follows the exact same convention:
pretty, owner, tablespace, and schema_qualified are plain boolean
parameters with DEFAULT values, using PG_GETARG_BOOL() directly rather than
parse_ddl_options().  The shared DdlOptType / DdlOption / parse_ddl_options
infrastructure is gone entirely.

*Filtering parameters:* *only_kinds* / *except_kinds* as text[]
Based on review feedback the filtering parameters(*include/exclude*) have
been revised:
The two mutually-exclusive filter arguments are now named *only_kinds* and
*except_kinds* (matching the SQL set-operation vocabulary) and take text[]
rather than a comma-separated text value (e.g. only_kinds =>
ARRAY['index','foreign_key']).  This provides type safety and allows
named-argument syntax.

*Note*: only and except are the keywords, and I couldn't find any better
name. Suggestions are welcome.

The *v14* patch is ready for review/test.
