PostgresqlMetadata works very-very slowly #199
Description
in the class Zend\Db\Metadata\Source\PostgresqlMetadata method loadTableNameData works very slowly.
It generate query:
SELECT "t"."table_name", "t"."table_type", "v"."view_definition", "v"."check_option", "v"."is_updatable"
FROM "information_schema"."tables" t
LEFT JOIN "information_schema"."views" v ON "t"."table_schema" = "v"."table_schema" AND "t"."table_name" = "v"."table_name"
WHERE "t"."table_type" IN ('BASE TABLE', 'VIEW') AND "t"."table_schema" = 'public'
query result: 438 rows 2160 ms!
Why make a selection from the database all the tables when we need all the data on a single table?
Perhaps you need to cache?
