The constructor accepts a number of parameters: |

The path to F<psql>. By default, this will look for F<psql> in your path and |
123
|
|
|
|
|
|
|
throw an error if it cannot be found. |
124
|

134
|
|
|
|
|
|
|
|
135
|
|
|
|
|
|
|
The host to use when connecting to the database. Optional. |
136
|
|
|
|
|
|
|
|
137
|
|
|
|
|
|
|

|
|
=item * require_ssl |
142
|
|
|
|
|
|
|
|
143
|
|
|
|
|
|
|
If this is true, then the C<PGSSLMODE> environment variable will be set to |
144
|
|
|
|
|
|
|
"require" when connecting to the database. |
145
|
|
|
|
|
|
|
|
146
|
|
|
|
|
|
|
=item * quiet |
147
|
|
|
|
|
|
|
|
148
|
|
|
|
|
|
|
This defaults to true. When true, the "-q" flag is passed to psql whenever it |
149
|
|
|
|
|
|
|
is executed. |

154
|
|
|

|
|
|
155
|
|
|
|
|
|
|
This method runs a command against the specified database. You must pass one |
156
|
|
|
|
|
|
|
or more options that indicate what psql should do. |
157
|
|
|
|
|
|
|
|
158
|
|
|
|
|
|
|
This method also accepts optional C<stdin>, C<stdout>, and C<stderr> |
159
|
|
|
|
|
|
|
parameters. These parameters can be any defined value that could be passed as |
160
|
|
|
|
|
|
|
the relevant parameter to L<IPC::Run3>'s C<run3> subroutine. |
161
|
|
|
|
|
|
|
|
162
|
|
|
|
|
|
|
Most notably, you can pass scalar references to pipe data in via the C<stdin> |
163
|
|
|
|
|
|
|
parameter or capture output sent to C<stdout> or C<stderr> |
164
|

|
|

|
|

|
=head2 $psql->execute_file( database => ..., file => ... ) |
166
|
|
|
|
|
|
|
|
167
|
|
|
|
|
|
|
This method executes the specified file or files against the database. C<file> |
168
|
|
|
|
|
|
|
should either be the path to a single file as a string or C<Path::Class::File> |
169
|
|
|
|
|
|
|
or an arrayref of such paths. You can also pass additional options via the |
170
|
|
|
|
|
|
|
C<options> parameter. |
171
|
|
|
|
|
|
|
|
172
|
|
|
|
|
|
|
This method also accepts optional C<stdin>, C<stdout>, and C<stderr> |
173
|
|
|
|
|
|
|
parameters, just like the C<< $psql->run() >> method. |
