For example, when you&#8217;re not using the table anymore. Dropping obsolete tables can free up database storage.<\/p>\n\n\n\n<p>The PostgreSQL <code>DROP TABLE<\/code> statement, a simple and powerful tool, deletes a table from the database.<\/p>\n\n\n\n<p>Here&#8217;s the syntax of the <code>DROP TABLE<\/code> statement:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-1\" data-shcb-language-name=\"PostgreSQL SQL dialect and PL\/pgSQL\" data-shcb-language-slug=\"pgsql\"><span><code class=\"hljs language-pgsql\"><span class=\"hljs-keyword\">DROP<\/span> <span class=\"hljs-keyword\">TABLE<\/span> &#91;<span class=\"hljs-keyword\">IF<\/span> <span class=\"hljs-keyword\">EXISTS<\/span>] <span class=\"hljs-built_in\">table_name<\/span>;<\/code><\/span><small class=\"shcb-language\" id=\"shcb-language-1\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">PostgreSQL SQL dialect and PL\/pgSQL<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">pgsql<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>In this syntax:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>First, specify the name of the table you want to delete after the <code>DROP TABLE<\/code> keywords.<\/li>\n\n\n\n<li>Second, the <code>IF EXISTS<\/code> option provides you with the control to remove the table only if the table exists, ensuring your actions are secure.<\/li>\n<\/ul>\n\n\n\n<p>If you delete a table that does not exist, PostgreSQL will issue an error.
