[bug] PostgreSQL Copy Table error

Hello all. My company uses PostgreSQL and I was thrilled when I noticed recently that HeidiSQL added Postgres support!! It does appear to be quite buggy though at the moment. I imagine this is the appropriate place to report bugs? If not I'll gladly direct them elsewhere.

I was attempting to duplicate the structure of a Postgres table using [right-click] Create New -> Table copy. I selected just the Columns and Indexes, gave it a new name, and when I clicked OK received an error. The output is below.

Yes, PostgreSQL support is quite incomplete, and I am also not so a specialist in PG than I am in MySQL. But yes, this is the place to report bugs, and I can try to fix that somehow. Not sure how but I guess that IS.TABLES query mentioned above is meant for getting existing table names in the target database.

The query in question is a check whether the target table exists, and if yes, Heidi asks whether it shall overwrite it with the new table copy. The query works here on my local PG v9.3.4 server, so I'm wondering which version of PG does not own the information_schema.tables view. Which is your PG version?

Hm, The db is on 9.2.12.

But I'm wondering if this is because of the double-quotes? When I run the query:
select * from information_schema.tables
I see the table details; if I run:
select * from "information_schema.tables"
I get the error message:

ERROR: relation "information_schema.tables" does not exist
SQL state: 42P01
Character: 15

Ah,
select "table_name" from "information_schema"."tables"
works, but
select "table_name" from "information_schema.tables"
doesn't

Fixed in r4975 - please update to HeidiSQL's latest build.

The problem seems to be that PG wants the exact character case of table and column names when they're in quotes. Heidi selected from the table "TABLES", which is now "tables". Same goes for the column name "TABLE_NAME".

This just fixes one bug amongst others in that dialog. Creating indexes fails here in some cases. And foreign keys are never detected yet.

Thanks ansgar! This worked for me, my indexes were created successfully as well.
