Synopsis ¶

Copy data between a file/program and a PostgreSQL table.

Requirements ¶

The below requirements are needed on the host that executes this module.

psycopg2

Parameters ¶

Parameter Choices/Defaults Comments

ca_cert

string

Specifies the name of a file containing SSL certificate authority (CA) certificate(s).

If the file exists, the server's certificate will be verified to be signed by one of these authorities.

aliases: ssl_rootcert

columns

list / elements=string

List of column names for the src/dst table to COPY FROM/TO.

aliases: column

copy_from

path

Copy data from a file to a table (appending the data to whatever is in the table already).

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.

login_unix_socket

string

Path to a Unix domain socket for local connections.

login_user

string

Default:

"postgres"

The username used to authenticate with.

options

dictionary

Options of COPY command.

See the full list of available options

port

integer

Default:

5432

Database port to connect to.

aliases: login_port

program

boolean

Choices:

no ←
yes

Mark src/dst as a program. Data will be copied to/from a program.

See block Examples and PROGRAM arg description

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

Choices:

allow
disable
prefer ←
require
verify-ca
verify-full

Determines whether or with what priority a secure SSL TCP/IP connection will be negotiated with the server.

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 postgres account 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.

Examples ¶

  postgresql_copy:
    copy_from: /tmp/data.csv
    dst: acme
    columns: id,name
    options:
      format: csv

- name: >
    Copy text vertical-bar-separated data from file /tmp/data.txt to bar table.
    The NULL values are specified as N
  postgresql_copy:
    copy_from: /tmp/data.csv
    dst: bar
    options:
      delimiter: '|'
      null: 'N'

- name: Copy data from acme table to file /tmp/data.txt in text format, TAB-separated
  postgresql_copy:
    src: acme
    copy_to: /tmp/data.txt

- name: Copy data from SELECT query to/tmp/data.csv in CSV format
  postgresql_copy:
    src: 'SELECT * FROM acme'
    copy_to: /tmp/data.csv
    options:

- name: Copy CSV data from my_table to gzip
  postgresql_copy:
    src: my_table
    copy_to: 'gzip > /tmp/data.csv.gz'
    program: yes
    options:
      format: csv

- name: >
    Copy data from columns id, name of table bar to /tmp/data.txt.
    Output format is text, vertical-bar-separated, NULL as N
  postgresql_copy:
    src: bar
    columns:
    - id
    - name
    copy_to: /tmp/data.csv
    options:
      delimiter: '|'
      null: 'N'

Return Values ¶

Common return values are documented here, the following are the fields unique to this module:

Key	Returned	Description
dst string	always	Data destination. Sample: /tmp/data.csv
queries string	always	List of executed queries. Sample: ["COPY test_table FROM '/tmp/data_file.txt' (FORMAT csv, DELIMITER ',', NULL 'NULL')"]
