Note: I have removed the LOCK TABLES and UNLOCK TABLES statements as they are not necessary in PostgreSQL. I have also changed the foreign key constraint names to follow the PostgreSQL syntax. Additionally, I have changed the published column in the post table from a TINYINT to a BOOLEAN. Finally, I have quoted the "user" table name as it is a reserved keyword in PostgreSQL.

Here's the PostgreSQL equivalent of the post_meta table:
sql
Copy code
--
-- Table structure for table `post_meta`
--
DROP TABLE IF EXISTS "post_meta";
CREATE TABLE "post_meta" (
"id" BIGSERIAL NOT NULL,
"postId" BIGINT NOT NULL,
"key" VARCHAR(50) COLLATE "pg_catalog"."default" NOT NULL,
"content" TEXT COLLATE "pg_catalog"."default",
CONSTRAINT "pk_post_meta_id" PRIMARY KEY ("id"),
CONSTRAINT "uq_post_meta" UNIQUE ("postId", "key"),
CONSTRAINT "fk_meta_post" FOREIGN KEY ("postId") REFERENCES "post" ("id")
);
Note that the conversion process involved replacing the backticks () with double quotes (") to enclose the table and column names. The AUTO_INCREMENTattribute was replaced with theBIGSERIALdata type. TheUNIQUE KEYsyntax was replaced with theCONSTRAINTkeyword and theUNIQUE` constraint. Finally, the character set and collation settings were omitted as PostgreSQL uses a different default character set and collation.
Please convert these into postgresql env

Here's the conversion of the post_tag table structure to PostgreSQL:
sql
Copy code
--
-- Table structure for table `post_tag`
--
DROP TABLE IF EXISTS "post_tag";
CREATE TABLE "post_tag" (
"postId" bigint NOT NULL,
"tagId" bigint NOT NULL,
PRIMARY KEY ("postId","tagId"),
CONSTRAINT "fk_pt_post" FOREIGN KEY ("postId") REFERENCES "post" ("id"),
CONSTRAINT "fk_pt_tag" FOREIGN KEY ("tagId") REFERENCES "tag" ("id")
);
CREATE INDEX "idx_pt_tag" ON "post_tag" ("tagId");
CREATE INDEX "idx_pt_post" ON "post_tag" ("postId");
Note that I've replaced the backticks around table and column names with double quotes, since that's the syntax used in PostgreSQL. Also, I've removed the DEFAULT CHARSET and COLLATE clauses since PostgreSQL handles character sets differently.
Please convert these into postgresql env

rewritten
Here's the PostgreSQL version of the user table:
--
-- Table structure for table `user`
--
DROP TABLE IF EXISTS "user";
CREATE TABLE "user" (
"id" SERIAL PRIMARY KEY,
"firstName" varchar(50) DEFAULT NULL,
"middleName" varchar(50) DEFAULT NULL,
"lastName" varchar(50) DEFAULT NULL,
"mobile" varchar(15) UNIQUE,
"email" varchar(50) UNIQUE,
"passwordHash" varchar(32) NOT NULL,
"registeredAt" timestamp NOT NULL,
"lastLogin" timestamp DEFAULT NULL,
"intro" text,
"profile" text
);
Note that I removed the collation specification because PostgreSQL uses a different system for collation. Also, the AUTO_INCREMENT attribute was replaced with the SERIAL data type, which automatically generates a sequence for the id column. Finally, I made the mobile and email columns UNIQUE constraints, which is equivalent to the UNIQUE KEY in MySQL.
