title: Error reading postgresql 8.4 database with pgadmin 4
body: <p>I have an old postgreSQL database running locally on my machine (localhost:5432), with postgreSQL 8.4</p>
  
  <p>In the process of converting to a more modern version, I first tried to install a more modern version of postgreSQL, namely a pgSQL 12.2.4 with pgAdmin 4, freshly installed using the entrepriseDB installer.</p>
  
  <p>At that point, I can access my 8.4 database with pgAdmin III, without any issue.</p>
  
  <p>However with pgAdmin 4, I cannot access my tables. Namely: I can connect to the server, and view a list of databases. And I can "open" a database and see all the objects in it, and everything seems to be there, the tables are there. But whenever I try to read the properties of a table, I get the following error:</p>
  
  <p>ERREUR: entrée manquante de la clause FROM pour la table « typ »
  LINE 57: typ.typrelid AS typoid,</p>
  
  <p>(sorry, french locales)</p>
  
  <p>I can, however count rows and view the data (right click -> view/edit data) but I cannot run SQL on any of the tables (on pain of the same error).</p>
  
  <p>The problem occurs with all the tables in several databases hosted on the same server - some are postGIS and some are plain, no difference.</p>
  
  <p>Thanks for the hints !</p>
