It's almost certainly a case-folding issue. It'd help if you posted the output of: \d in the database of interest. At a guess, what's happening is that you have a mixed-case table name. Let's say it's called "Fred". You're trying to run: pg_dump --table "Fred" dbname The shell consumes the double-quotes during argument processing, so what pg_dump actually sees is three arguments: --table Fred dbname Because of case-folding rules, table names that are not double-quoted are folded to lower-case. This means that the table names: Fred FRED fred FrEd are all interpreted as meaning the table "fred" (lower case). If you need to preserve case, you need to protect the double quotes from consumption by the shell, so you send the argument "Fred" to pg_dump. In your command line above, you would change --table "$ESQUEMA.$Nametable" to --table "\"$ESQUEMA\".\"$Nametable\"" ... adding a pair of escaped double-quotes around both the table and schema names that the shell does NOT consume. The outer double-quotes need to be retained in case the table or schema names contain shell meta-characters and/or spaces.
