Error Cannot Copy To/from Client In Pl/pgsql
Here's a characteristic example: create or replace function build_table (integer) returns integer as ' begin execute ''copy foo to stdout;''; return 1; end' language plpgsql; The result: /* cbbrowne@[local]/dba2 COPY TO can also copy the results of a SELECT query. First thing you would need to check is server status(using below commands), if server is not running, start it and try to connect. -bash-4.1$ /opt/PostgreSQL/9.3/bin/pg_ctl -D /opt/PostgreSQL/9.3/data/ status pg_ctl: server is sql postgresql csv copy plpgsql share|improve this question edited May 9 '14 at 7:46 user272735 5,88763464 asked May 7 '14 at 16:02 jasonmclose 4861820 To be fair, the reason http://oncarecrm.com/error-cannot/error-cannot-copy-file-etc-hosts-openvz.html
anton-kotenko commented Feb 12, 2013 \copy is not a part of sql syntax, it's special command, that is handled by psql, not by database server. You signed in with another tab or window. Rather use the second form with quote_literal() or format() with %L. –Erwin Brandstetter May 10 '14 at 12:50 add a comment| Your Answer draft saved draft discarded Sign up or The security restriction on COPY is there for a good reason, so simply over-riding it as though you know better is clearly not the way to go.
I think there is a bigger problem. Often you know that you don't have any use for queries running more than x times. The above seems to be the real problem. Thanks for taking the time to right this down.
In a more recent CVS, Tom points out that this elicits a more meaningful error message: ERROR: cannot COPY to/from client in PL/pgSQL CONTEXT: PL/pgSQL function "build_table" line 2 at execute See:
Not sure what you mean with this? Alternatively, you can add "SET search_path TO pg_catalog,pg_temp[,…]" to your function header (you can append more schemas to this path as necessary, or just force callers to qualify their table_name). The table grows a lot, current have more than 13,000,000 records, plus have many indexes, that the reason why is slow to insert That's why i tried to use copy. http://postgresql.nabble.com/Interesting-COPY-edge-case-td1931789.html Any help will be appreciated.
We can work around this reasonably, but the "unexpected error -2" elicits some curiosity I'd like to satisfy. (I bounced it off one of the others that aren't off on vacation, Any help will be appreciated. Of course a NULL does not look like an array, so the message was issued before the data was tested on NULL values. I've explained the principles involved, and welcome feedback of anything I might have missed. :) Export from database to file CREATE FUNCTION export_temp_table_to_csv_file(table_name text, file_name text) RETURNS VOID LANGUAGE plpgsql --

You would need to look at your "listen_addresses" parameter in postgresql.conf file, check if you are set this to allow the other servers to connect. -bash-4.1$ /opt/PostgreSQL/9.3/bin/psql -p 5435 -U postgres One of our folks ran into the same situation, and the same surprise.

This could be built in to a shell script, and not needing to copy data to/from the server might be an advantage, but building it into a more complex data import/export Regards and thanks in advance. -- Adrian Klaver [email protected]
In the case of COPY, it is up to your function to constrain what users can do - the tighter the restrictions the better - while allowing for all the scenarios
The guards will also be informed that accepting food or drink from any other source will result in execution."
This is why there are a couple of special cases in the COPY command: COPY FROM STDIN and COPY TO STDOUT.

There's not an easy way to change that buffer size currently it appears.
Now, I'm having two issues with these: - in native OLEDB, if an error happens when executing an SQL statement, I cannot close the connection (ADO Connection.Close won't actually close it) It turns out that you can't use parameterized arguments when the copy command is used (at least that's the case with python as the stored proc language).
