I understand, So there is no way to fetch table in a single query. The only
way is :
1. Connect demo
2. Execute the query 'SELECT n.nspname as Schema, c.relname as Name,
CASE c.relkind WHEN 'r' THEN 'table'
pdc_uima=# select table_name from information_schema.tables where
table_schema='pdc_uima';
table_name
(0 rows)
But filtering on 'public', it gives the result , :
pdc_uima=# select * from information_schema.tables where
table_schema='public';
table_catalog | table_schema |

Below is what i did -
1. pg_start_backup()
2. rsync the data dir
3. pg_stop_backup()
I believe the backup is valid because, i was able to bring up the cluster

While replying to another query, something struck me as interesting that

People here often raise issues where preparing a parameterised query and

Dear all,

Hi,
I'm trying to optimize a query where I have two tables that both have a
