Issue #11051 has been updated by Ken Barber.
Okay - gotcha.
So interestingly, the double backslashes actually work for me:
$dbname = "foo-bar"
exec { "database-${dbname}":
command => "/usr/bin/mysql -uroot -pmyrootpassword -e \"create database
\\`${dbname}\\`;\"",
unless => "/usr/bin/mysql -uroot -pmyrootpassword -e \"show databases\"
|/bin/grep ^${dbname}$",
logoutput => on_failure,
}
You say this returned some error?

Bug #11051: Unrecognised escape sequence '\`' in file (escaped backtick in
manifest)
https://projects.puppetlabs.com/issues/11051
Author: Egon Kastelijn
Status: Investigating
Priority: Normal

Category:
Target version:
Affected Puppet version:
Keywords: puppet escape sequence backtick
Branch:
We are developing MySQL recipes to make Puppet create and manage databases.
In order to create a MySQL database the database-name needs to be surrounded by
backticks:
exec { "database-${dbname}":
command => "/usr/bin/mysql -uroot -p${mysql_password} -e \"create
database \`${dbname}\`;\"",
unless => "/usr/bin/mysql -uroot -p${mysql_password} -e \"show
databases\" |/bin/grep ^${dbname}$",
require => Class["mysql::server"],
}
The catalogs runs fine, and the MySQL database is nicely created on the node.
The problem is that the PuppetMaster complains about an unrecognised escape
sequence:

sequence '\`' in file /etc/puppet/prod/modules/mysql/manifests/database.pp at
