Parameters¶
| Parameter | Choices/Defaults | Comments |

columns
list
/ elements=string
|
List of column names for the src/dst table to COPY FROM/TO.

Mutually exclusive with copy_to and src.
aliases: from |
|
|
copy_to
path
|
Copy the contents of a table to a file.
Can also copy the results of a SELECT query.
Mutually exclusive with copy_from and dst.
aliases: to |
|
|
db
string
|
Name of database to connect to.
aliases: login_db |
|
|
dst
string
|
Copy data to dst=tablename from copy_from=/path/to/data.file.
Used with copy_from only.
aliases: destination |
|
|
login_host
string
|
Host running the database.
|
|
|
login_password
string
|
The password used to authenticate with.

Default: "postgres"
|
The username used to authenticate with.
|
|
options
dictionary

Options of COPY command.
See the full list of available options https://www.postgresql.org/docs/current/sql-copy.html.
|
|
|
port
integer
|
Default: 5432
|
Database port to connect to.
aliases: login_port |
|
program
boolean
|
|
Mark src/dst as a program. Data will be copied to/from a program.
See block Examples and PROGRAM arg description https://www.postgresql.org/docs/current/sql-copy.html.
|
|
session_role
string
|
Switch to session_role after connecting. The specified session_role must be a role that the current login_user is a member of.
Permissions checking for SQL commands is carried out as though the session_role were the one that had logged in originally.

|
src
string
|
Copy data from copy_from to src=tablename.
Used with copy_to only.
aliases: source |
|
|
ssl_mode
string
|
|
Determines whether or with what priority a secure SSL TCP/IP connection will be negotiated with the server.
See https://www.postgresql.org/docs/current/static/libpq-ssl.html for more information on the modes.
Default of

trust_input
boolean
added in 0.2.0 of community.postgresql
|
|
If
no, check whether values of parameters are potentially dangerous.It makes sense to use
no only when SQL injections are possible. |
Notes¶
Note
Supports PostgreSQL version 9.4+.
COPY command is only allowed to database superusers.
If check_mode=yes, we just check the src/dst table availability and return the COPY query that actually has not been executed.
If i(check_mode=yes) and the source has been passed as SQL, the module will execute it and rolled the transaction back but pay attention it can affect database performance (e.g., if SQL collects a lot of data).
The default authentication assumes that you are either logging in as or sudo’ing to the
postgresaccount on the host.To avoid “Peer authentication failed for user postgres” error, use postgres user as a become_user.
This module uses psycopg2, a Python PostgreSQL database adapter. You must ensure that psycopg2 is installed on the host before using this module.
If the remote host is the PostgreSQL server (which is the default case), then PostgreSQL must also be installed on the remote host.
For Ubuntu-based systems, install the postgresql, libpq-dev, and python-psycopg2 packages on the remote host before using this module.
The ca_cert parameter requires at least Postgres version 8.4 and psycopg2 version 2.4.3.
