A bug was found on the consultation of the postgres schemas that I could see the visible table schema, there were two identical table in different schemas

Even after setting:
- SET TO search_path public;
the problem remained.

Example:
(Schema, table) historic.test
(Schema, table) public.test

In a regular SQL.
- Select * from test
the component associated to the table and not in historic.test public.teste that this case is correct.

SOLUTION TO THE PROBLEM
Zeos 6.1.5 version:
############################

FileName: ZDbcPostgreSqlMetadata.pas

Function:
TZPostgreSQLDatabaseMetadata.GetColumns function (Catalog: string;
SchemaPattern: string; TableNamePattern: string;
ColumnNamePattern: string): IZResultSet;

.....

SQL: = SQL + 'AND n.nspname LIKE''' + EscapeQuotes (SchemaPattern) +'''';

----------------------------
Replace with:
----------------------------

if SchemaPattern <>''then begin
SQL: = SQL + 'AND n.nspname LIKE''' + EscapeQuotes (SchemaPattern) +'''';
end else begin
SQL: = SQL + 'AND pg_table_is_visible (c.oid)';
end;

Write it in a special section http://zeos.firmos.at/viewforum.php?f=25

Better to do patches in the form of "diff" file

For example using TortoiseSVN make the patch is very easy
