Postgresql tables exists but getting relation does not exist when querying

Question

I have a postgresql db with a number of tables  If I query   SELECT column name FROM information schema columns WHERE table name  my table     I will get a list of the columns returned properly    However  when I query    SELECT   FROM  my table     I get the error    ProgrammingError  relation  my table  does not exist  SELECT   n    FROM  my table  n       Any thoughts on why I can get the columns  but can t query the table  Goal is to be able to query the table

The error can be caused by access restrictions  Solution  GRANT ALL PRIVILEGES ON DATABASE my database TO my user

You have to include the schema if isnt a public one  SELECT   FROM  lt schema gt   my table    Or you can change your default schema  SHOW search path  SET search path TO my schema    Check your table schema here  SELECT   FROM information schema columns     For example if a table is on the default schema public both this will works ok  SELECT   FROM parroquias region SELECT   FROM public parroquias region   But sectors need specify the schema  SELECT   FROM map update sectores point

I had the same problem that occurred after I restored data from a postgres dumped db   My dump file had the command below from where things started going south       SELECT pg catalog set config  search path       false     Solutions    Probably remove it or change that false to be true  Create a private schema that will be used to access all the tables    The command above simply deactivates all the publicly accessible schemas   Check more on the documentation here  https   www postgresql org docs 9 3 ecpg-connect html

I hit this error and it turned out my connection string was pointing to another database  obviously the table didn t exist there  I spent a few hours on this and no one else has mentioned to double check your connection string

In my case  the dump file I restored had these commands  CREATE SCHEMA employees  SET search path   employees  pg catalog   I ve commented those and restored again  The issue got resolved

I was using pgAdmin to create my tables and while I was not using reserved words  the generated table had a quote in the name and a couple of columns had quotes in them   Here is an example of the generated SQL  CREATE TABLE public  quot Test quot        id serial NOT NULL      data text NOT NULL      updater character varying 50  NOT NULL       quot updateDt quot  time with time zone NOT NULL      CONSTRAINT test pk PRIMARY KEY  id     TABLESPACE pg default   ALTER TABLE public  quot Test quot      OWNER to svc newnews app   All of these quotes were inserted at  quot random quot    I just needed to drop and re-create the table again without the quotes  Tested on pgAdmin 4 26

You can try   SELECT    FROM public  my table    Don t forget double quotes near my table
